Photos: Celebs Get Spooked At Los Angeles Haunted Hayride

Who doesn't love a good scare? Celebs, including Rumer Willis, Zac Efron, Krysten Ritter, Russell Simmons and Derek and Julianne Hough showed up at the 8th Annual Los Angeles Haunted Hayride Premiere Night at Griffith Park on October 10, 2013.

There, they were menaced by various ghouls, giant evil clowns and other scary characters.

Zac Efron showed up with Hairspray costar Brittany Snow. New couple alert? Or, as People says, is she still dating Teen Wolf actor Tyler Hoechlin?

Of course there was a press line because every event is a photo op, right? Derek Hough also shared a photo of Efron, Snow and Hairspray director Adam Shankman.
