Tina Fey Admits She Was a 'Mean Girl' in High School

The actress recently admitted it was a "coping mechanism."

"I was, I admit it openly," she told Net-a-Porter's The Edit. "That was a disease that had to be conquered."

Fey, 45, said that later on in life she realized why she became a bully.

"It's another coping mechanism," she said. "It's a bad coping mechanism, but when you feel less than ... 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," she quipped.

Being mean wasn't Fey's only coping mechanism. The actress said she also used comedy as a way to cope with her personal issues.

"For me it was about hitting age 13 and realizing, 'OK, I'm not going to glide by on looks. I'm a normal-looking person, but that's not going to be where my bread is buttered.' The desire to be funny -- because you are never actually quite sure if you really are funny -– is a coping mechanism, another way of ingratiating yourself," she said.

Fey couldn't help but gush about her friend and co-star.
