New York, Dec 2 Tina Fey's signature facial scar is the result of a childhood slashing, it has been revealed.

The '30 Rock' star has never publicly addressed the origin of the faint marking, which runs down her left cheek.

Now, Fey's husband, Jeff Richmond, has revealed in an interview with Vanity Fair that the 38-year-old comedienne was attacked by a stranger in a violent slashing incident when she was five.

"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," the New York Daily News quoted Richmond, as saying.

"That scar was fascinating to me. This is somebody who, no matter what it was, has gone through something. And I think it really informs the way she thinks about her life," he added.

Fey said she doesn't like to going back to the incident because "it's impossible to talk about it without somehow seemingly exploiting it and glorifying it."

However, she added, she's never felt unattractive because of the scar.

"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," she said.

"Everybody's got a better side," she added. (ANI)
