Lizzy Caplan, fondly remembered as Janis in Mean Girls and a doomed V addict on True Blood, is heading to the FOX hit New Girl for a three-episode arc.

According to TVLine, Lizzy will play Julia, a gorgeous gal with a master's degree in art history who impresses Nick (Jake Johnson) with her cultured wit and charm. Smitten, he invites her to Schmidt's (Max Greenfield) birthday party, only to begin to worry about what she'll think of his friends.
