Forget “hot” – Paris Hilton is Supernatural.

The celebutante will portray a monster on the October 8 episode of The CW’s Supernatural — and series creator Eric Kripke says the guest appearance was a great coup for the show.

“I don’t think we’re gassing up the motorcycle to jump the shark yet,” Kripke told Entertainment Weekly’s Michael Ausiello on Friday. “It’s a fun, irreverent episode about modern celebrity. [Fans] should withhold judgment until they see it.”

“[She plays] a monster who takes the form of Paris Hilton,” he added.

Supernatural writers were convinced the heiress was the guest star who could best mock the concept of celebrity status; they were delighted when she agreed to appear.

“We never expected in a million years that she would do it, but I spoke to her and she got the joke immediately and signed on quickly,” he revealed. “I give her a lot of credit for being a hell of a good sport. The fact that she was game to play the part speaks volumes about her sense of humor.”

Paris Hilton guest stars on Supernatural Thursday, October 8 on The CW.
