Yeah, there was a Mean Girls 2. But its more of a knockoff of the original movie. I dont think Tina Fey had anything to do With that one.
This New "Mean Girls 2" is the idea of using the priginal cast and setting the story like 10 years Down the line. It could be awesome. Im thinking It might be a bit Desperate housewives/Mean Girls mix.
This is how i Picture them 10 years later
Karen Smith : Trophy Wife
Gretchen Wieners: Housewife, hair still full of Secrets
Regina George: Probably president of all sorts of assosiations and Clubs, still fabulous but evil.
Cady Heron: ??
