The Winchesters will always have Paris — Hilton, that is.

The socialite is set to guest-star in the fifth episode of Supernatural's new season. The role won't require too much research.

"Paris Hilton is playing a demonic creature that takes the form of... Paris Hilton," said creator and executive producer Eric Kripke said in a statement. "It'll be a fun, irreverent episode and we here at Supernatural are thrilled that Paris agreed to do it."

Hilton is equally thrilled: "I love the show Supernatural. It rocks! So excited!" she tweeted, adding a smiley face at the end.

The guest spot will reunite the heiress with Jared Padalecki, her House of Wax co-star.

Hilton's episode, dubbed "American Idol," airs Oct. 8. Supernatural returns Sept. 10 at 9/8c.
