Ever since the release of her joint album with Tony Bennett, "Cheek to Cheek," the "Applause" singer has been showing the world a completely different side, both of herself and particularly of her music abilities - and now, as Lady Gaga's wedding to fiancé Taylor Kinney approaches, she's also showing off her jazz star power with the coolest wedding guest of all!

Anyone with even the most remote mind of jazz would dream of having Tony Bennett perform in such a happy occasion, but, as a collaborator and personal friend of the legendary crooner, it's hardly any surprise at all that he'll be putting those famous pipes to work in Lady Gaga's wedding.

As Entertainment Tonight Online reports, now that the controversial singer is planning her marriage, it seems like one of the first things to clarify was who would be singing at Lady Gaga's wedding - and Mr. Bennett was more than willing to take up the challenge!

The New York Post's Page Six recently interviewed the crooner, famous for his rendition of the nostalgia classic "I Left My Heart In San Francisco," as he gushed about Lady Gaga's wedding to Kinney, speaking about how happy he was for the 28 year-old pop star because she was tying the knot with a "very wonderful man."

"'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," said Bennett, according to The Daily Mail, when he was asked about Lady Gaga's wedding, then adding that they'd invited him to sing during the reception and he was only too happy to oblige.

Although, of course, Kinney's currently most famous for being the man who popped the question to Lady Gaga (whose real name Stefani Germanotta), he's also making a career for himself as an actor, having starred in the Oscar-nominated film "Zero Dark Thirty" and currently working in "Chicago Fire."

After getting engaged only a month ago, there's still no date for Lady Gaga's wedding - but so far it sounds like it'll be a lovely reception!
