Katy Perry is a funny chick when she's just Katherine Elizabeth Hudson, her real name, but when she's playing a character, she's pretty hilarious! Katy has appeared in SNL skits before, when she was the musical guest, but she has never hosted Saturday Night Live.

Most recently, Katy has shown her flare for acting in her "Last Friday Night" video, which was released in June. Katy's doing big things this year!

She got married a year ago, was the first woman to have five no.1 singles on an album, and she's wrapping up a sold out 122-city world tour... She's unstoppable.
