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?
