Prince Harry meets Lady Gaga and Tony Bennett
Royalty meets Mother Monster.
On Monday, Britian's Prince Harry met Lady Gaga and Tony Bennett when the duo performed at London's Royal Albert Hall for a benefit show.
The whole gang, along with Sir Elton John, posed for a batch of photos together, too.
Proceeds from the concert went to supporting the charity WellChild, which helps seriously ill children and young people in the U.K.
"We think you are fantastic," Gaga, 39, told Harry, 30, according to People.
In turn the prince told the 88-year-old Bennett, "I can't believe you have the energy. I don't know how you do it!"
"Your mum was a good friend of mine. I did many benefits with her," Bennett told Harry about his late mother, Princess Diana.
Gaga and Bennett have been performing together as part of their "Cheek to Cheek" tour.
