Tina Fey became immortalized on 30 Rock as Liz Lemon, the “New York third-wave feminist, college-educated, single-and-pretending-to-be-happy-about-it, over-scheduled, undersexed, [who will] buy any magazine that says ‘healthy body image’ on the cover and every two years [she’ll] take up knitting for…a week” (as poetically described by Alec Baldwin’s Jack Donaghy). It was no secret the character was somewhat based on Fey, but it’s apparently accurate down to their high school rep as, for lack of a less obvious phrase, a “mean girl.”

Fey, who wrote the film Mean Girls (adapted from Rosalind Wiseman’s Queen Bees and Wannabes), revealed the truth of her teenage years in an interview with The Edit.

“Marlene is my best girlfriend. She was Prom Queen at high school, based on the fact that she is so incredibly likeable – very pretty, but never the Mean Girl. I was [the Mean Girl], I admit it openly. That was a disease that had to be conquered. It’s another coping mechanism – it’s a bad coping mechanism – but when you feel less than (in high school, everyone feels less than everyone else for different reasons), in your mind it’s a way of leveling the playing field. Though of course it’s not. Saying something terrible about someone else does not actually level the playing field. If I meet a girl of 14 or 15 today who is that kind of girl, I am secretly, in my body, afraid. Even though I’m 45.”
