The former Glee gal plays Hester -- a.k.a. "Neckbrace" as Emma Roberts' Chanel Oberlin so cruelly nicknames her -- who is an overly eager pledge for the Kappa Kappa Tau sorority. Lea's co-stars told ET that they just can't get enough of this character.
"She makes me laugh all day!" Emma said. ""Literally, there was a scene where she doesn’t have any dialogue and she was just standing right here and I would have to look over her head. I was like, 'I'm sorry, I'm not being rude, but if I look at you I will laugh so hard.' I couldn't even take it, it was just so funny!"
