Lady Gaga is working on new music with Mark Ronson, according to... Lily Allen!

The British pop star spilled the info at the 2015 British Fashion Awards red carpet. "I was meant to be in the studio with Mark Ronson tomorrow and he cancelled on me because Gaga's here," Allen revealed, adding: "I'm just going to turn up anyway, and be like, 'Hi Gaga!'"

Gaga and Ronson have known each other for years and back in 2010, she inspired the young producer to sing on his records. "I was recording the vocal on her song for Wale, and we were talking, and she was like, 'Have you ever taken singing lessons?', and I said no," Ronson recalled. "And she said, 'Well, you should try, you never know.' And so I did and I went to see her vocal coach. So, if it's really horrible, you can blame Lady Gaga for it."

Mark Ronson is known for his work with Robbie Williams, Christina Aguilera, Adele, Lily Allen, Paul McCartney and many others. He also produced several tracks on Amy Winehouse's hit album Back to Black, including "Rehab," for which he won a Grammy for "Record of the Year." Ronson scored his first number one single last year, when his track "Uptown Funk" featuring Bruno Mars was released to widespread critical and commercial success.
