For those of you who missed the show last night, once of the most unexpected groups gave us one of the most fun performances of the night! Check out the video above to see LMFAO close the show with “Sexy and I Know It” and “Party Rock Anthem.”

As if the colorful and energetic performance wasn’t enough, cameos from both Justin Bieber and David Hasselhoff really sealed the deal! Although having to leave his adorable lade Selena in the audience must’ve been tough, check out his crazy yellow pants!

What did you think of the performance which ended it pretty minimal clothing? Did you think it was crazy fun or just crazy? Let us know on twitter!
