"They invited me to do it and, of course, I will," pagesix.com quoted Bennett as saying.

The 88-year-old, who collaborated with Gaga, 28, on the album "Cheek to Cheek" last year, further praised the couple -- who have dated each other for more than three years -- and their blossoming relationship.

Asked what he thought of the wedding, he said: "I love it. She's marrying a very wonderful man, very talented and very handsome. I think he's going be highly successful in films. He's a very nice person."
