A Brief History of Katy Perry at the VMAs

Katy Perry is slated to host the VMAs on Sunday, which means we should probably expect something big and colorful on the red carpet -- I'm wondering if, given her current hair, she'll go full punk -- and let's face it, probably a horde of costume changes. I'm quite excited for the spectacle, even if, or possibly especially, it's cockamamie.

In honor of that, I thought a stroll down memory lane that's SPECIFIC to Katy might be a fun exercise. If only it were actual exercise. I guess we could... read it on our phones while doing squats?
