Lady Gaga Surprises Crowd And Duets With Tony Bennett At Montreal Jazz Fest

Lady Gaga made a surprise appearance during Tony Bennett's set at the Montreal Jazz Festival on Tuesday, July 1. The pair performed several cuts - including "But Beautiful" and "Lush Life" - from their upcoming collab, Cheek to Cheek.

The following day, Gaga played a tour date of her own on her ongoing Artpop tour.

"When she sings great standards, she does it with such emotion," Bennett says of the upcoming album.

"It will surprise people by the quality of her voice when making quality songs. We sing a duet again on the album, but also separately. With this album, I think she will become bigger than Elvis Presley! Of course we recorded the album in New York.

Cheek to Cheek is expected to hit in September.
