I've never seen the movie but I looked at the cast. In the first one, I would be partial to Tina Fey as I've watched her on Saturday Night Live ! Although Amanda Seyfried has those really pretty eyes. It sure wouldn't be Lindsay Lohan ! Yuk ! Looking at the cast of Mean Girls 2 , I didn't recognize anyone in it.
I guess I would say Katie cause she can be nice and mean. That's how her character was in the movie.
