Paris Hilton to Guest Star on Supernatural

Paris Hilton - yes, Paris Hilton! - will appear on an episode of Supernatural this season.

Not much is known about this former sex tape star's role on The CW series, but she'll guest star on episode five.

Because producers are aware of her reputation, a source close to the show tells E! News that fans should relax and "trust [show runner] Eric Kripke."

Okay. We'll try. But if she gives one of the Winchester boys an STD, we're gonna be pissed!
