Lindsay Lohan is making a career out of a teenage nightmare -- changing high schools.

She plays a New Yorker who moves to the suburbs in the recently released "Confessions of a Teenage Drama Queen" and will follow by portraying a home-schooled student experiencing the classroom for the first time in "Mean Girls," opening April 30. Then it's on to "Dramarama" and "Gossip Girls," both of which, more or less, are about changing schools.

Lohan has yet to shoot the latter two films but is quick to note the differences between her current hit and "Mean Girls."

"It's a little bit older, it's a little more mature than ['Confessions'] and I think it's time for me to do that kind of thing," Lohan said.

What separates "Mean Girls" from standard high school dramas is the film's screenwriter, "Saturday Night Live" writer and actress Tina Fey. The "Weekend Update" co-anchor penned the script based on an article in The New York Times Magazine titled "Girls Just Want to Be Mean," about the harsh realities of cliques.

"She's brilliant, and the script is so hysterical," Lohan said. "It's not an 'SNL' film, but we had a lot of the 'SNL' people in it. And it was really cool just to be able to work with them and work with such great people on the set, because they're so funny and they bring so much to the script and so much to the characters that it's so amazing to be around them."

Along with Fey, who plays a guidance counselor, "Saturday Night Live" alumni Tim Meadows, Ana Gasteyer and Amy Poehler star in "Mean Girls."

Lacey Chabert ("Daddy Day Care"), Rachel McAdams ("The Hot Chick") and Lizzy Caplan ("Freaks and Geeks") also co-star, while Lohan's "Freaky Friday" director, Mark S. Waters, is at the helm.

"It's basically about a girl whose parents travel around the world and she has no idea what school is like," Lohan said. "She has no idea what cliques are and what the social scene is like. She meets these two kids who are really nice to her, [then] meets this other group of girls who are the mean girls, and they kind of control the school. And she becomes one of them and falls into the wrong crowd and becomes a mean girl and loses friends in the process."

Lohan's character becomes a target for the mean girls when she attracts the interest of one of their ex-boyfriends. The girls then go to war, spreading malicious gossip, posting nasty Internet messages, banishing each other from lunch tables and, of course, giving the silent treatment.

"It's kind of like 'Heathers' in a way," Lohan said, referencing the 1989 classic featuring Winona Ryder, Christian Slater and Shannen Doherty. "Except there's no killing in it or anything. It's a fun movie, kind of like a dark comedy."
