Photos: Lady Gaga and R Kelly Simulate Sexual Acts on Stage.

Lady GaGa took over the Saturday, November 16 episode of "Saturday Night Live". In addition to making appearance as a guest host, the 27-year-old star performed her newest single called "Do What U Want". Wearing a sparkly suit and a blonde wig, GaGa joined forces with collaborator R. Kelly when she delivered the first live performance of the song. Both singers were seen putting their hands on one another before simulating some sexual acts on stage.

Lady Gaga and R Kelly left little to the imagination as they suggestively performed sexual acts on each other. The 27-year-old made sure her debut hosting duties were not easily forgotten as she writhed around on stage, grinding with the Bump N’ Grind hitmaker as they sang their duet Do What U Want.
At one point in the performance, the R&B singer threw Gaga over his shoulder before putting her down and spanking her bum.

Halfway through the song, the controversial singer dropped to her knees in front of R Kelly much to the shock of the audience.
