Rebel Wilson and Adam Devine won in the "Best Kiss" category and recreated the scene from Pitch Perfect 2 on stage. The fans in attendance went wild as the duo locked lips.

And when Melissa McCarthy won the Comedic Genius Award, she couldn't find her way to the stage and was eventually carried there.

Alexander Skarsgard, who is about to play Tarzan, went with a "no pants" look when he walked on stage. He told the crowd: “I think it looks classier that way.”

The night was not just filled with goofs and gags, but also with special moments.

Will Smith won the Generation Award. He was introduced by Halle Berry and Queen Latifah who discussed his longevity and how he's fought for diversity in Hollywood.

The Oscar-nominated actor got emotional when he accepted his award, telling the crowd: “I really want to say I am humbled...

"I’m dedicated to being a light in this world. I just want to help in this world, there are a lot of people suffering in this world. I am dedicated until I die to light and to love.”

Straight Outta Compton won "Best True Story” and star Jason Mitchell made a swipe at the Oscars after the movie failed to be recognized by the Academy.

“I would like to thank the Academy. Oh my bad, I would like to thank MTV, I mean MTV,” he said.

NWA, the rap group on which the movie is based, was inducted into the Rock and Roll Hall of Fame earlier in the weekend.
