After participating in a couple of sketches, Mother Monster took the stage along with R.Kelly to perform their new song "Do What U Want" and let's just say the temperature probably rose a couple of degrees in the SNL studio!
The song begins with Gaga singing and dancing a little over-enthusiastically in a cleavage-baring bodysuit before the R&B star joins her on stage.
Things get a little strange when he throws her over his shoulder like a sack of potatoes, but when he finally puts her down, Gaga gives us a taste of her twerking skills, Miley Cyrus-style.
Check out the clip above to see their performance and tell us what you think. Too sexy?
