22 Lindsay Lohan Movies to Celebrate Her Comeback in "Falling For Christmas"

The 2004 teen comedy "Mean Girls" tells the story of a 16-year-old new girl in an American high school learning to navigate cliques, hierarchies, and bullying. Lohan plays said new girl, Cady Heron, who was previously homeschooled in Africa. Cady befriends loners, impresses her teachers, and gains a crush. But when she unwittingly ends up joining the popular girls known as The Plastics, backstabbing, teenage drama, and memorable one-liners ensue.
