Katy Perry to Guest Star on Raising Hope (Thanks to Her Real-Life Bestie)

The pop star plays Rikki, a prison guard who claims to be a friend from Sabrina's (Woodward) past. In the episode, Sabrina gets arrested for participating in a protest, and gets sent to the slammer for two weeks. (Will they stop at nothing to keep Sabrina and Jimmy [Lucas Neff] apart?!)

Perry tweeted the above photo today, saying: "I hope I don't get type-cast." Doesn't she look pretty?!

"Shannon Woodward is my best friend," Perry 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.' [Showrunner] Greg [Garcia] was nice, but I hope he's not secretly sabotaging my potential future career by typecasting me in the role of just a looker, so that I would never be able to play anything more challenging."

"Shannon Woodward told me that her friend Katy was interested in doing an episode and I thought, ‘Why not? Let's do your friend Katy a favor,'" Garcia said in a hilarious statement. "Then she came in and did a terrific job. She was hilarious. And now people are telling me that Katy is also a singer. I sincerely hope that her appearance on the show helps her get her singing career off the ground. It's a tough business."

Something tells us she'll do all right.
