The long-rumored Lady Gaga and Kendrick Lamar collaboration has finally arrived!

"PARTYNAUSEOUS" was written by Gaga and Kendrick back in 2012 and was scheduled to be included in the rapper's debut album, but was later scrapped due to creative differences between the artists' teams.

"I apologize to the fans that this situation is confusing," Gaga said. "When I collaborate with an artist I work solely with them, not with their camps or management. It's purely organic and creative. I love Kendrick dearly as a friend, but was not willing to compromise musically to the changes his team was making to my music. He's a good kid, its just sometimes a mad city."

Congratulations to Lady Gaga, Cynthia Germanotta and their Born This Way Foundation for winning ADL's Making a Difference Award for championing positive social change and efforts to combat bullying, bias and bigotry!

"Thank you so much for this wonderful award," Mother Monster said in a video message. "I am so proud to accept it on behalf of the Born This Way foundation and my partner, who is also my mom, Cynthia. This is such an incredible honour."

The Anti-Defamation League was founded over a century ago "to stop the defamation of the Jewish people and to secure justice and fair treatment to all." No Place for Hate is one of the many campaigns launched by the organization that fights bigotry and encourages racial and religious tolerance in schools.

Lady Gaga and Tony Bennett continue their Cheek to Cheek tour with two sold-out shows at the Queen Elizabeth Theatre in Vancouver.

Among the many highlights of the evening was Gaga's beautiful rendition of "Bang Bang (My Baby Shot Me Down)," during which she showed off her impressive pipes and left the audience in awe. Watch the video below...

Little Monsters, get ready to put some paws up... literally! Lady Gaga announced today that she'll be launching a puppy product line, which will include fashion, organic food, and accessories. 

The big announcement was made by Mother Monster's puppy Asia on Instagram, who "stole" her mom’s phone for the day. "I love to eat while I sketch my ideas for the fashionable puppy line I'm starting," Gaga posted on behalf of Asia. "I get hooked up with the finest in puppy products, so I really have a knack for what’s quality. My vision is to find creative and functional ways for pets and their owners to bond!"

In another post, she announced that the line will also include organic dog food: "Organic grain-free local farm ingredients are the best for our body and brain. That’s what I eat! That’s why I’m inspired to also create A Pet Food Line."

Finally, Asia wrote: "I can't speak, but I try my piggy best to show 'Thank you' and 'I love you' with my eyes. Every dog is forever a puppy and should be loved like one."

According to Billboard, Lady Gaga will serve as creative visionary and artistic director for the collection of chic and fashionable apparel, bowls, toys and accessories. 

"This is not just about crazy outfits for dogs,” Gaga's manager Bobby Campbell said. “It’s about giving pet parents and pet owners a fun and creative way for protecting their pets, as well as fun clothes to display on Instagram (because Gaga loves doing that)."

He added that a portion of proceeds from the collection will go to “locally-based organizations that do great work with real pets,” specifically grassroots organizations that do not have the funds larger that national ones do.

Lady Gaga has debunked internet speculation that she's pregnant with her first child.

Mother Monster decided to respond to rumors about changes in her body during a sold out Cheek to Cheek show at Concord Pavilion. "People have been wondering if I'm pregnant," Gaga told the crowd. "I say to them, 'No, I'm not, I'm just fucking almost 30."

Back in 2013, Gaga told Sirius XM listeners: "I want to have tons of kids, actually. I think at least three. I really want to have a family and I really want to nurture my children. To be honest, having my own kids will be like having three little monsters with me all the time. They probably won't be fans, in fact they'll probably hate my music, who knows."

"I love being Mother Monster too," she added. "That's my first job right now and pretty happy with it."

Lady Gaga has once again proved that her voice is strong enough to fill an entire arena even without a microphone.

On Thursday night, Gaga and Tony Bennett brought their Cheek to Cheek world tour to Concord, CA where they sang over 20 jazz standards at a sold-out show at Concord Pavilion.

Among the best moments of the night was Gaga's emotional rendition of Cher's "Bang Bang (My Baby Shot Me Down)," towards the end of which she went mic-less, filling the arena with her massive pipes. As soon as the performance ended, the audience rose up in an immediate standing ovation.

Lady Gaga surprised fans during the second night of the Cheek to Cheek tour at the Hollywood Bowl when she performed a beautiful rendition of Edith Piaf's signature song "La Vie En Rose." Gaga charmed the audience with her powerful vocals as she sang the 1946 classic, wearing a pink dress designed by her sister Natali Germanotta.

“When they told me that I was gonna be singing at the Hollywood Bowl I got so excited because they told me I’d be singing here with Tony," she shared with the sold-out crowd. "What I told them was 'Sometimes, you gotta make your own dreams come true. It’s up to you to make it happen.' So I’d like to dedicate this song to my parents who are here tonight. And to my sister Natali, 'cause my dream is to sing my favorite song in a pink dress made by my sister."

Caitlyn Jenner, formerly known as Bruce Jenner, revealed herself to the world on the cover of Vanity Fair on Monday. The first ever photos of Jenner, taken by famed photographer Annie Leibovitz, accompany an inspirational interview, in which she talks about her transition.

Lady Gaga immediately took to her Twitter account to applaud Caitlyn for her brave photo shoot. "Caitlyn, thank you for being a part of all of our lives and using your platform to change people's minds." Mother Monster wrote. "The beauty on the inside is now also on the outside. God bless you and the whole family for sharing it with us."

Just days after playing two sold-out shows at the Hollywood Bowl with Tony Bennett, Lady Gaga headed to Serbia to see her fiancé Taylor Kinney. The actor is currently on the set of The Forest, a supernatural thriller starring Natalie Dormer, which is directed by Jason Zada.

"I am lucky to be with somebody that has a great job," Gaga told Howard Stern back in 2013. "We don't have any rules about calling each other at certain times. We'll go days at a time without talking. Then we'll talk every day. The way that it really works is, we trust each other. He's on his journey, and I'm on mine, and we're gypsies—and then when we're together we're really in love."

Gaga arrived in Belgrade on Tuesday evening and is expected to stay in the country until the end of the week before she heads to London to perform at the Royal Albert Hall.

Sarah Paulson is a Little Monster! The actress had an adorable freak out when Lady Gaga tweeted about her excitement to work with Sarah on the upcoming season of American Horror Story.

"I haven't met Lady Gaga, but the highlight of my life probably ever was when she tweeted me," Paulson told E! Online. "People started texting me going, ‘Oh my god!’ I was like, ‘I have had contact with Lady Gaga! Have you?!’ I’m very excited. I'm gonna cry!"

Speaking of her role in American Horror Story: Hotel, she added: "I'm the baddest girl in town, that's all I can say. It's a first for me! I've never really played a character with the real dark side, so I'm excited."

American Horror Story: Hotel is set to film next month and start airing in October. How excited are you for the show? Sound off in the comments below!

Lady Gaga is in London! After spending the week with her boyfriend Taylor Kinney, who is currently on the set of a movie in Serbia, Mother Monster touched down at Heathrow earlier today and was greeted by a massive crowd of screaming fans outside her hotel.

Lady Gaga is set to play two sold-out shows at the legendary Royal Albert Hall with Tony Bennett on Monday and Tuesday nights. The Monday concert will benefit WellChild, a national charity working to support children and young people with complex health needs. 

"WellChild is thrilled that Lady Gaga and Tony Bennett are supporting WellChild through this concert," said a spokesperson for the charity. "The proceeds will be a massive boost to our work to support seriously ill children and their families across the UK."

It was announced earlier this month that Prince Harry, who is a patron of WellChild, will be in the audience.

When Lady Gaga arrived to a massive crowd of screaming fans in London yesterday, she received a special gift from a Little Monster — a fan book titled "Seven Years of Love," full of beautiful messages from fans from around the UK.

Gaga took the time to read through the book today, just hours before her Royal Albert Hall show with Tony Bennett, and one particular message caught her attention. It read: "There were always this kind of fight between you and fame and with this new jazz era I have the feeling that this is gone. I have the feeling that you finally found and realized who you really are. You look very strong, strong enough now."

Lady Gaga shared the words with her eight million Instagram followers, saying: "This is why my fans are different from other fans. Our bond over life, love, and identity, after it passes through endless shallow channels of machines, the end is a very rich substance. Fame is petty in comparison to believing in someone. Thank you for all the books and poetry. Monsters you always remind me."

She later added: "You give me so much energy, I can't wait to perform for you with Tony tonight. And I dream of the morning we share in my new music together. When the new era of Monsters begins again. And the cycle continues."

Lady Gaga has teamed up with democratic New York Governor Andrew Cuomo to push for a new campus sexual assault policy at all of the state's colleges and universities. In a joint op-ed piece, published by Billboard magazine on Monday, the two called campus sexual assault an "unacceptable epidemic," and urged lawmakers to pass the bill called "Enough is Enough" to help reduce assaults and ensure justice for victims.

"Sexual assaults are not just violations of local campus rules – they are crimes that must be treated as such," the pair wrote. "Victims must know that they have the right to call the police, and they must be supported in their recovery, regardless of whether that could mean negative publicity for their school."

They added: "We have a responsibility to the young men and women of this country to stand up against sexual violence everywhere. Everyone – from lawmakers and educators to advocates like Born This Way Foundation and the students themselves – need to join forces on this issue. Together, we must create the scaffolding necessary to foster the mental, emotional, and physical health of all young people."

Lady Gaga and Tony Bennett brought their Cheek to Cheek world tour to the United Kingdom and played London's iconic Royal Albert Hall as part of a fundraising gala for WellChild, a national charity working to help children and young people with complex health needs receive quality medical care.

Prince Harry, who is a patron of the charity, met with the duo for a quick chat before they went on stage. Gaga told the prince: "We are so happy to be here tonight and be of any help, we think you are fantastic. And thank you for bringing it here so we can support you."

Explaining how they collaborated on their jazz album, Bennett said: "I heard her personally and said we have to get together." Harry told him: "I can't believe you have the energy, I don't know how you do it." But Gaga joked: "He runs circles round me. Wait until we get on stage!"

During the show, Gaga dedicated Edith Piaf's "La Vie En Rose" to the charity. "I would like to dedicate this song tonight to the wonderful organization WellChild and Prince Harry," she told the crowd. "Together they are raising awareness and money for children and it takes care of them for a very long period of time making sure they're looked after. I think if you have a voice and you choose to use it for good things, that is something to be applauded."

Gaga added, "So tonight, let's cheers to them, to doing good things. Because if anyone can afford a ticket to be here tonight, you're doing pretty fucking good."

The show reportedly raised more than £100,000 for WellChild.

Lady Gaga has joined Apple Music!

"I'm excited to be a part of it."

We are sorry to announce that Tony Bennett and Lady Gaga had to cancel tonight's show at London's Royal Albert Hall because Tony is ill. We will update this post when more information is available.

Update (9:20 PM, GMT +1): Tony Bennett was forced to cancel the second of two sold-out shows with Lady Gaga at the Royal Albert Hall in London after coming down with a flu virus. "Sorry to not be singing in London tonight," Tony said in a tweet. "I love my fans in the UK and appreciate all the well wishes to get over this flu quickly."

Mother Monster took to her Twitter as well, saying: "Hey everybody! Don't worry about Tony, he's ok! That's just showbiz sometimes. We'll catch you next time, we got you!"

Get well soon, Tony!

Even though Lady Gaga had to cancel her show with Tony Bennett at the Royal Albert Hall, that did not stop her from singing jazz on Tuesday night. After a soundcheck at the iconic venue, during which Tony fell sick, Gaga headed straight to Ronnie Scott's jazz club for a surprise performance for London's jazz lovers.

Lady Gaga and the Brian Newman Quartet played an impromptu set of Cheek to Cheek favorites, including "Lush Life" and "Bewitched, Bothered and Bewildered."

By the time Lady Gaga finished her performance, the street was filled with tens of fans and paparazzi trying to get a glimpse of the star. Watch a video of Gaga leaving Ronnie Scott's below...

A staff member of the Soho club commented that "she was funny, friendly and her band was great," while lucky fan later tweeted: "Gaga at Ronnie Scott's was the best night of my entire life. She is one supremely talented person. Beautiful!"

Alice Cooper was so impressed with Lady Gaga's versatility as an artist that he thinks she should make a hard rock album now.

In a new interview, the rock legend said: "She has developed into something really unique. I mean, she created this character named Gaga, she exploited it on every level, made it work. And the songs were good, that was the deal, she wrote her own songs. And then she performed them and she didn't give up on it."

"Then she gets on the Oscars, and does Julie Andrews totally straight," he continued. "When I saw that, I went, 'She just went to another level.' She just went to a Streisand sort of level, where she can still do the insane Lady Gaga, but she can also do this now. She's kinda turned into a butterfly. But you gotta like that, that's a real talented person right there."

Cooper added: "The record with Tony Bennett, who would've thought of that? I mean, how wild is that? Now, if I was her, I would make a really hard rock record right now."

Monsters, do you agree with Alice? Let us know in the comments below!

American Horror Story star Finn Wittrock has revealed why he's excited about Lady Gaga's appearance in the upcoming season of the show.

The actor, who played fan-favorite character Dandy Mott on Freakshow, told Variety magazine about his reaction when he first heard that Mother Monster would be joining the show: "I was like, 'Perfect!' Ryan [Murphy] always has a way of outdoing himself. It's hard to keep surprising people when each season is so surprising. He very wisely makes a big awesome casting choice to get people intrigued. This was the epitome of that."

"The thing about her, with her great theatricality and the gratuity of her own image, it actually makes a lot of sense for her to be on this show," Finn added. "The show is heightened and gothic and that’s sort of what she is. It’s a good omen for the way the season will turn out."

American Horror Story: Hotel is set to film next month and start airing in October. No word yet on whether Finn Wittrock will be returning for the upcoming season.

American Horror Story's fan favorite Jessica Lange, who will not be returning for the show's new season, has shared her thoughts on Lady Gaga's casting on the series.

"She'll be surrounded by all those great actors," the actress told The Daily Beast. "The same ones I had the great opportunity to work with. I have no idea if she’s an actor or not. But I'm sure it will all work out. I don't know what the season is, what they're doing, what the premise is, who the characters are. But all I can say is she’s going to have good writing and she’s going to have great actors to work with. It's a good start."

Lange added: "I'll miss the show, but I think in some way I had never intended to do more than one season, and then reconsidered and decided to do three more. But, you know, I felt like I had come to the end of it. I'd love to work with Ryan [Murphy] again sometime on a different project."

American Horror Story: Hotel is set to film in July and start airing in October. Earlier this week, the show's creator Ryan Murphy revealed that Lady Gaga will be caught in an on-screen love triangle between Matt Bomer and Finn Wittrock.

Lady Gaga is now officially an icon! Mother Monster was honored with the first-ever Contemporary Icon Award for "attaining an iconic status in pop culture" at the 2015 Songwriters Hall of Fame Induction and Awards in New York on Thursday.

"It could be said that this honor was created with Lady Gaga in mind. She has enjoyed monumental popularity on the charts, on radio, TV and the Internet, not to mention the continuous press coverage she has generated," Songwriters Hall of Fame President Linda Moran said. "She is a consistent hit maker who has surprised everyone by proving to be as adept with the great standards as she is with her own songs."

"This has to be my favorite award I've ever gotten," Gaga told fans on Instagram. "I still remember dragging my keyboard up the of my walk up to play songwriter showcases and apply to be in songwriting forums where I could play my music for other artists and we'd critique each other. I was 15 then. I'm 29 now. In my head this is how I planned it, following all the roads I thought were right. But I'm not sure I thought about what I'd do if I never made it. Cuz I'd forever be trying."

At the Gala, Lady Gaga sang Linda Perry's "What's Up," in front of celebrity guests such as Toby Keith, Cyndi Lauper, Michael Buble, Zac Brown and Perry herself. Watch below...

American Horror Story creator Ryan Murphy has teased details about the show's upcoming season to Deadline.

When asked if there will be any musical numbers, Ryan said: "No. People, keep saying to me, 'What numbers are they singing, what numbers are they singing,' and I say there will be no numbers. The interesting thing is we cast a lot of singers this season but I like that singers, for the most part, are always great actors because they know how to sell a story through song, through a scene. I think that's why Gaga was excited about it; it's not something that she's ever done before. It's a pure acting part. I think people expect that she's going to be sitting in a bar in a white silk gown sort of singing songs — she is not."

"The upcoming season that we're doing is much more horror-based; it's much more dark," he continued "It's about a theme and an idea that's very close to my heart that I've always wanted to do that's a little bloodier and grislier I think than anything that we've done before; it's straight horror this year."

Speaking of the set, Murphy added: "We're building this incredible six-story Art Deco hotel on the Fox lot. Everybody in the show is very excited about this season, Sarah Paulson and Evan Peters particularly because in every season thus far they've always been sort of the heroes, the good guy or the good lady so to speak, and this season they're playing absolute evil villains so they're very excited about that and I think people will really enjoy it, and the Gaga part is bananas good."

American Horror Story: Hotel starts filming in three weeks and will air in October. Monsters, what do you expect from Lady Gaga's first major television role? Sound off in the comments below!
