Katy Perry

Katy Perry came prepared for splatter when she and a bunch of gal pals attended the 4th annual Los Angeles Haunted Hayride VIP Premiere Night, which took place at Hollywood’s Griffith Park on Sunday. According to People magazine, the group headed into a haunted maze, where they remained for about a half hour. "She seemed to be having a ton of fun and shared lots of laughs with her friends,” an onlooker told the magazine. “She loved being scared by all of the characters each time they snuck up on her!"
