Katy Perry Prom Party Crasher [PHOTOS]

Katy Perry is all wrapped up in the teenage dream. The pop singer surprised a group of Australian high school students Friday night but crashing their prom.

Katy Perry's appearance was a total surprise, Perry just happened to be staying at the same hotel the prom was taking place in while on her Downunder tour.

It was only appropriate for the California girl to make her appearance while her hit single California Gurls played. She had an impromptu performance, singing the hit for the students and even hung around for a few minutes mingling with the kids and dancing. It was definitely a prom to be remembered.
