Lady Gaga and Tony Bennett crashed New York's Frank Sinatra School of the Arts yesterday (June 16) to surprise students with an impromptu performance and masterclass.
The collaborators and friends discussed jazz music and creativity in front of a 700-strong audience, with the conversation moderated by NBC presenter Lester Holt.
Gaga and Bennett then performed covers of Billie Holiday and Cole Porter, alongside a number of other classic American songs, before duetting on 'I Can't Give You Anything But Love', which they slow-danced to.
Veteran singer Bennett then praised Gaga to the audience, saying: "When I first heard Gaga sing, my reaction was that she is going to be bigger than Elvis. She is so bright and intelligent and she has it. In jazz you either got it, the syncopation, the rhythm or you don't, and when I heard Gaga I said she's got it!"
