This was certainly not Rachel McAdams and Ryan Gosling, round two.

Pitch Perfect 2 stars Rebel Wilson and Adam DeVine won the MTV Movie Awards' infamous Best Kiss honor and they revealed that, in real life, they have "absolutely no sexual chemistry."

"We have none. Zero. Zilch. Nada. I'm not turned on by her soft, pillowy lips," DeVine told the crowd, as Wilson chimed in, "And I'm not aroused by his little Cabbage Patch face and his tight little bubble butt."

And then, well, this happened...

The duo's sloppy make out session quickly escalated as they rolled around on the floor -- and resulted in a hilarious "outfit malfunction." Though Wilson's crotch was censored during the broadcast, Fat Amy herself was actually wearing shorts underneath her dress. Which is to say: Everything was covered down under.

Good luck topping this, next year's Best Kiss winners.

Charlize Theron, Kendall Jenner and Gigi Hadid were just a few of the stars who absolutely slayed the MTV Movie Awards red carpet. Check out all the best looks in the video below.
