Is Ashley a secret Pretty Little Liars prankster?

Here at J-14, we've been hearing whispers that a Pretty Little Liar cast member has been stirring up trouble behind the scenes, so when we hung out with the cast at the season finale viewing party in N.Y.C., we got to the bottom of the mystery and found the culprit. "I am!" Ashley Benson confessed only to J-14 about secretly pulling pranks on set. "i do so many! "I like to put things on people's clothes when they're not looking, and then they'll be walking around all day with something on their back." Who's her favorite victim? "Ian Harding," Ashley admits. "I put up girl posters in [his] dressing room and I'll do other weird things like that." Ashley must have picked up Hanna's sneaky wasps on the show- watch your back, Pretty Little Liars stars!
