Watch Lady Gaga & Tony Bennett's 'Lady Is A Tramp' Duet

On Tony Bennett's new album Duets II he performs "The Lady Is A Tramp," with Lady Gaga (wonder how they decided on that song). In the new music video, Gaga scats, declares her love for the Yankees, and gives her performance a bit of retro flair (or a retro as one can be with blue hair).
