Lady Gaga & Tony Bennett's Duet 'The Lady Is A Tramp' Emerges Online!

NEW YORK (Top40 Charts) Lady GaGa's duet with legendary crooner Tony Bennett has emerged online!

The collaboration follows the release of Tony Bennett's duets with Mariah Carey, Natalie Cole, Norah Jones and Amy Winehouse, which were released this week off his forthcoming 'Duets II' album, out Sept. 20.

The classic has been covered by everyone from legends like Frank Sinatra and Ella Fitzgerald, to the cast of 'Glee,' and the Gaga-Bennett rendition is just as showstopping as the best of them!

As expected, Gaga's collaboration is much more upbeat than Amy Winehouse's somber last song, 'Body and Soul,' her duet with Bennett that debuted yesterday (Sept. 14) on what would have been the late singer's 28th birthday.

Bennett's 'Duets II' album tracklisting is as follows:
Andrea Bocelli - 'Stranger In Paradise'
Michael Buble - 'I Wanna Be Around'
Mariah Carey - 'When Do The Bells Ring For Me'
Natalie Cole - 'Watch What Happens'
Sheryl Crow - 'The Girl I Love'
Aretha Franklin - 'How Do You Keep The Music Playing'
Josh Groban - 'This Is All I Ask'
Faith Hill - 'The Way You Look Tonight'
Norah Jones - 'Speak Tonight'
Lady Gaga - 'The Lady Is A Tramp'
KD Lang - 'Blue Velvet'
John Mayer - 'One For My Baby (And One More For The Road)'
Willie Nelson - 'On The Sunny Side Of The Street'
Queen Latifah - 'Who Can I Turn To'
Alejandro Sanz - 'Yesterday I Heard The Rain'
Carrie Underwood - 'It Had to Be You'
Amy Winehouse - 'Body And Soul'
