Lady Gaga Sings a Showtune! Hear the Pop Icon Croon 'The Lady is a Tramp' with Tony Bennett

Pop star Lady Gaga once was a musical theater hopeful studying at NYU, and the chart-topper memorably shared her Broadway dreams with the cast of American Idiot last year. Now it's finally time to hear her croon an actual showtune: the Rodgers and Hart standard “The Lady is a Tramp” from Babes In Arms. Her singing partner here is none other than the legendary Tony Bennett and the track will be featured on his new Duets II album, in stores on September 20.
