No, seriously, Katy Perry has a new music video out for her song, “Birthday,” and it’s for reals just like Jackass. If I’m getting this right, Katy threw on a disguise, crashed five different birthdays, and proceeded to just wreck the sh!t out of them. But then she pulled off the disguise and revealed she was Katy, so I guess that kind of made up for it? I mean, everyone signed off on the release forms, so I’m guessing they’re cool with it. Probably. “On one hand, I’m emotionally traumatized. On the other hand, famous boobies!” Either way, the song’s pretty sweet.
