Lady Gaga hosts Saturday Night Live
The Applause singer dropped to her knees in front of R Kelly while they sang their duet Do What U Want, and he did push ups over her as she lay on the stage, as well as spanking her, according to Metro.
Gaga, 27, also poked fun at herself and the criticism from some that she is a poor version of Madonna by taking part in a sketch where she pretended to promote an album called WHAAAT! Worst covers of all time.
In it, she dressed up as Madonna for a cover of Express Yourself and began singing her own hit, Born This Way, which some critics had accused her of ripping off from Madonna.
She also took part in a sketch called Waking Up With Kimye where she played a nerdy Apple store employee, according to E!
With other members of the show's cast playing Kanye West and the Kardashians, Gaga went up against the actor playing Kim Kardashian in a contest called Kim Wore It Best, where the singer's character compared her frumpy outfits to the reality star's glamorous ensembles.
Gaga, who is known for her outlandish outfits, joked: "Honestly, I don't care about fashion. I think people who try too hard with their outfits are maybe hiding something. Like come on, dress like a person."
