Hubby reveals secret origin of Tina‘s trauma – her scar on her left cheek.

It’s something the 30 Rock thesp doesn’t talk about but that didn’t stop hubby Jeff Richmond from blabbing about it to glam mag Vanity Fair.

Tina was slashed by a stranger when the future SNL-er was only 5 years old. 

The incident happened right in front of her house, Richmond said.

Still, Tina Fey rather not talk about it much less think about it.

"I think it really informs the way she thinks about her life," Richmond told the mag.

Justifiable paranoid horror of humanity?
