...Lady Gaga and R. Kelly Perform ‘Do What U Want’ on ‘SNL’...

The freaks came out when Lady Gaga took over “Saturday Night Live.” In addition to hosting, the pop superstar performed her ARTPOP single “Do What U Want” with R. Kelly for the first time, and the result was nothing short of explosive. The two turned the stage into a bedroom as they rolled on the floor and put their hands all over one another.
Kellz carried Gaga over his shoulder, spanked her, and did push-ups on top of her during the raunchy performance.
“Just killed Saturday Night Live with @ladygaga .. Epic night, one for the ages,” tweeted Kellz.
After wiping the sweat off the stage, a solo Gaga returned later in the show to perform “Gypsy.” She started off playing a pink piano and then rocked out on guitar.
