Katy Perry Goofs Around Behind the Scenes of "Last Friday Night"

At the recent MTV Video Music Awards, Katy Perry took home three Moon Men for "Firework" and "E.T." Although her "Last Friday Night" lost to Britney Spears's "Till the World Ends" for Best Pop Video, the insanely colorful video still, well, pops! Even more so if you watch this behind-the-scenes vid with cool cameos by Darren Criss, Kevin McHale, Rebecca Black, Hanson, and more.

What do you think of the video? Tell us in a comment!
