Kristen Stewart graces the November cover of Allure and inside talks about her body image, evolving sense of style and shooting 'The Twilight Saga: New Moon' (opening November 20). Here are some highlights:

On her carefully disheveled appearance:
"I go outside, and I'm wearing a funky T-shirt and my hair is dirty, and people say, 'What's wrong with her? She needs to invest in a hairbrush.' I'm like, don't you get it? I'm not that girl! It's not like I was really clean cut last year."

On her weight worries:
"I don't exercise. I'm skinny fat. I worry about being too skinny. You should see my brother, he's, like, emaciated. We both just happen to be really skinny."

On the shots of her kissing Robert Pattinson in 'New Moon':
"This shot got everyone talking like I have some sort of great ass. But come on, I have a flat ass. I don't know what people are talking about."

The issue hits newsstands October 20.
