Zack + Miri
I was watching the deleted scenes in Zack & Miri, about 29-30 minutes in while they're trying to come up with a name for their movie I swear the girl in the coffee place is Harley Quinn Smith.
sharei thought so too, but there's no mention ot it in the credits or the imdb board!. shame i love her little cameos!
