'Pitch Perfect' star Rebel Wilson teamed up with Ellen Degeneres for one of the greatest rap duo moments the world has ever seen. You'll have to see it to believe it. Most people would probably agree that Rebel is hilarious in everything that she does, but throwing Ellen into the mix only makes this hilarious skit even better. I'm not sure if it's the matching jackets, the perfectly combined duo name or the topic of this song that makes me smile the most, but I do know that the whole thing is worth watching.

And I promise, you won't soon be forgetting the name Rebellen.

See the hilarity ensue here:
