Lady Gaga has been revealed as Tony Bennett's dueting partner for a very upbeat cover of 'The Lady Is A Tramp', which is taken from Bennett's forthcoming album, 'Duets II'.

'Duets II' will be released on September 20 and it features collaborations with Mariah Carey, Norah Jones and a very special song with Amy Winehouse. 

'Body and Soul' is the last track that Amy Winehouse recorded before she died on July 23 and the single was released on what would have been the singer's 28th birthday on September 14. 

'The Lady Is A Tramp' is now streaming online and the legendary Mr. Bennett said the following of Lady Gaga in an interview with the Guardian:

"She was so warm and friendly and sweet. I said, ‘I’d love to make a recording with you’. And she said, ‘Anything you want, I’ll do it.'"
