Did Katy Perry crash a prom?

Katy Perry is known for living life on a whim and being super spontaneous so when the singer heard her hit song "California Gurls" blasting from the ballroom at the hotel she was staying at in Australia, she couldn't help but walk right in. Katy grabbed the mic and started to sing along. Then she hit the dance floor to rock out to Beyonce's "Single Ladies" and even posed for photos with her fans before her security team whisked her away from the crowded party. Katy took to her twitter account to tell everyone about her sneaky little deed. "I totes just crashed a prom!!!" she proudly Tweeted.
