Janis Ian is one of the main characters in Mean Girls, portrayed by Lizzy Caplan. Janis was, up through eighth grade, best-friends with Regina George. She was the original choreographer for Santa's Helpers performance of Jingle Bell Rock, which they would perform at multiple Winter Talent Shows. Janis along with her friends, Damian Leigh and Cady Heron, plan to mess up Regina George's life. Janis introduces Damian as "Almost too gay to function," and it was only OK when she says it. Janis falls in love with Kevin Gnapoor, a mathlete.
Janis has black hair and wears black makeup as she is presumably goth. It is said that in eighth grade, she cut off her hair.
