Preparing for the enchanting evening ahead, Lady Gaga showed up at Jazz at Lincoln Center last night (July 28) to join forces with Tony Bennett and tape an upcoming special called “Cheek to Cheek Live.”

Accompanied by her grandmother Ronnie Bissett, Mother Monster was elegant in a black dress that showed off plenty of cleavage as she posed for photos with the legendary jazz singer.

“Cheek to Cheek Live” will air on PBS on October 24th, featuring selections from Gaga and Bennett’s collaboration album of the same name.

Tony told press, "The reason I chose to do (this project) with her is to show how wonderful she really sings. She's so uninhibited and talented, and has a wonderful talent of knowing how to improvise very well. She's really a great American singer."

"There might be 60 years between me and Tony, but there's no distance between us when we sing jazz. He calls me 'Lady,' and when I walk in the room, he stands up and so do all his friends. It's really of another time, and I hope with this music we can bring back that sentiment of love, kindness and joy that I'm getting to experience working with him every day. I just want to spread that around the world,” added Gaga.
