Katy Perry Has The Best House Party EVER in "Last Friday Night" Music Video

Sorry Gaga, but Katy Perry has dropped the best music video of the year.

I mean, how can "Last Friday Night" not be the best video of the year, with its crazy, balls-out 80's house party, an incredibly dorkified-turned-mallrat-hot Katy Perry, and cameos galore. I mean, Kenny G? Debbie Gibson? Rebecca Black?

There really isn't much to say except that Katy Perry delivered a blast of a video, which guarantees at least two weeks at #1 for her fifth single from Teenage Dream.

Yup, she's coming for Michael Jackson's record (he scored five #1 hits in the 80's with Bad).
