It looks like Rebecca Black isn't the only one who's got friday night fever. If you look closely, the internet sensation makes an appearance in Katy Perry's forthcoming 'Last Friday Night' music video.

But the 13-year-old may be in the doghouse if her parents catch wind of her cameo in the 80s flashback rager -- alongside a parent's worst nightmare, Perry, no less. The video shows a geeked out high school Perry getting her drink on before vomiting in a roller skate and having a pretty major wardrobe malfunction.
