It stands to reason that a Supernatural season built around a looming apocalypse would feature a guest turn by Paris Hilton. But series creator Eric Kripke says the casting stunt — airing next Thursday — doesn’t herald the end of the world as we know it.

“I don’t think we’re gassing up the motorcycle to jump the shark yet,” insists Kripke of the episode, which finds the hotel heiress playing “a monster who takes the form of Paris Hilton… It’s a fun, irreverent episode about modern celebrity. [Fans] should withhold judgment until they see it.”

Kripke insists the idea to cast socialite, Paris Hilton, originated in the Supernatural writers room and not in a CW executive suite.

“There was no pressure from the studio or network to do any stunt casting,” he says. “We had our wish list in the room of who would be the best spokesperson for a satirical monologue on modern celebrity and Paris Hilton was at the top of the list. 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. I give her a lot of credit for being a hell of a good sport,” he continues. “The fact that she was game to play the part speaks volumes about her sense of humor.”
