Although it seems like we’ve seen Tina Fey just about everywhere this year, there’s still a lot about the comedienne we don’t know. And for the first time, we’re finally learning more about one of the 30 Rock actress’ secrets.

In the January issue of Vanity Fair, Fey’s husband, Jeff Richmond, reveals the story behind the 38-year-old’s noticeable, yet subtle, scar. The facial imperfection was a result of a stranger slashing a then 5-year-old child. “It was in, like, the front yard of her house, and somebody who just came up, and she just thought somebody marked her with a pen,” Richmond said.

Understandably, the situation is not something Tina often brings up. “It’s impossible to talk about it without somehow seemingly exploiting it and glorifying it,” she explains. Fortunately for her, it’s something that she’s been able to work around. “It’s really almost like I’m kind of able to forget about it, until I was on-camera, and it became a thing of ‘Oh, I guess we should use this side’ or whatever. Everybody’s got a better side.” And when you’re the producer of your own show…you can use any side you’d like!
