Katy Perry to Guest Star on 'Raising Hope' as a Prison Guard!

She hosted Saturday Night Live and voiced a character in The Smurfs, but now Katy Perry is taking on a TV sitcom and guest starring on the Fox comedy Raising Hope. 

The pop star nabbed a role thanks to her real-life BFF and star of the show, Shannon Woodward, who asked Katy if she'd like to make a special appearace.

"Shannon Woodward is my best friend," Katy said in a statement. "A couple weeks ago, I was home, just toasting up a frozen chicken fillet when she called me up and asked if I wanted to do something ‘fun' for a change and try out a guest role on her TV show. I thought, ‘Sure, I have nothing else to do, and I like chillin' with my best friend.' "

Katy will play Rikki, a not-so-attractive prison guard — check out the photo Katy Tweeted — who looks after Sabrina (Shannon) after she's locked up in jail for two weeks following her involvement in a protest. Rikki claims that she knows Sabrina from their past and tries her best to make her "friend's" prison stay miserable. (This should be interesting.) OK!
