Mean Girls is a 2004 American teen comedy film directed by Mark Waters and written by Tina Fey. It stars Lindsay Lohan, Rachel McAdams, Lacey Chabert, and Amanda Seyfried. The film follows Cady Heron (Lohan), a naïve teenager who transfers to an American high school after years of homeschooling in Africa. Heron quickly befriends two outcasts, with the trio forming a plan to exact revenge on Regina George (McAdams), the leader of an envied clique known as the Plastics.

Lindsay Dee Lohan is an American actress, singer-songwriter, producer, and entrepreneur. Born in New York City and raised on Long Island, Lohan was signed to Ford Models at age three. She appeared as a regular on the soap opera Another World at the age of 10, and her breakthrough came in the 1998 Walt Disney Pictures film The Parent Trap. The film's success led to appearances in subsequent Disney projects; the television films Life-Size (2000) and Get a Clue (2002) and the big-screen productions Freaky Friday (2003) and Confessions of a Teenage Drama Queen (2004). Lohan's early work won her childhood stardom, while the teen comedy sleeper hit Mean Girls (2004) affirmed her status as a teen idol and established her as a leading Hollywood actress.
