If you thought Kathy Beth Terry was a hoot, then GET A LOAD OF THIS; Katy Perry's guest spot on US TV show Raising Hope have been revealed, showing Katy as a prison guard with a moustache, and lots of curly red hair.

That's one way to show your ex-husband what he's missing...

Ha! Katy's never been afraid to make fun of herself and it's great to see her enjoying the new look in these pictures.

She's said that the show's star (who happens to be one of Katy's BFFs) asked her if she'd like to pop by for a guest role.

"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," said K-Pez.

"I thought, ‘Sure, I have nothing else to do, and I like chillin’ with my best friend.' "

That sounds a good a reason as any, and plus, she STILL manages to look hot in a wig and fake moustache.

HOW IS THIS FAIR?!
