Lady Gaga and R. Kelly performed their sexy duet tonight at the AMAs 2013, singing their song "Do What U Want." Lady Gaga starts off pretending to be a secretary for the American Music Awards until she's interrupted by the President with a phone call from the Oval Office ... President R. Kelly.
The two carry on a sexy performance surrounded by dancers. Lady Gaga gets tossed around by a lot of Secret Service agent dancers as R. Kelly dances on top of his presidential desk.
At the end of the performance, President Kelly denies his involvement with Gaga. Lady Gaga then climbs atop a piano to finish the song on her own.
