It's a scary time of year to be in Hollywood!
Tons of celebs stepped out for Universal Studios Hollywood's Halloween Horror Nights over the weekend. Demi Lovato brought a bunch of pals with her, including BFF Hanna Beth, as did Dancing with the Star castmates David Arquette, Ricki Lake, Kym Johnson, Chaz Bono and Cheryl Burke.
Demi had such a great time at the amusement park that she even Tweeted about it, writing, "Just thinking about how excited I am for Halloween! Went to @HorrorNights @UniStudios this weekend and it was sooooo scary - loved it!!"
Wilmer Valderama, Elijah Wood and former One Tree Hill star Chad Michael Murray also hung out with some ghastly creatures.
But David with his old co-star, Scream's Ghostface Killer? Hands down the funniest duo of the day. Sorry, Ricki!
The event runs at Universal Studios through October 31.
See more pics of David, Demi, Elijah and all of the celebs who got to chill with zombies over the weekend below.
