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!
