And in this edition of "poor me", Kristen Stewart says the kids in school were so mean to her that she had to drop out at age 13 and get her GED.

"I couldn't relate to kids my own age," she said in a new interview with The Telegraph. "They are mean and don't give you any chance. Once you have done with school, you realise that it is just a smaller version of life, and really I have felt that I should have been an adult since I was aged about five."

Being quiet and shy, people mistook her aloofness for bitchiness, and that's when she was branded a "b*tch."

"I didn't walk around talking about doing movies," she says, "but then someone saw an old movie I was in, The Safety of Objects, and realized that the little boy in it [she played a tomboy] had grown up into this girl – me. And then I got a lot of, 'She's such a bitch!'"

"I was glad to leave school," Kristen says of her decision to leave the mean girls behind when she was just 13.

But even though she's just as mature today as she was when she was five, she's learned to keep her adult life very private.

"It doesn't matter how many times I've spoken to someone or how well they know me, I'm just not going to talk about that," she says when asked about boyfriend Robert Pattinson.

That's ok, KStew, we can still enjoy watching your relationship play out on the Twilight series!
