Kristen Stewart discusses life at the centre of the Twilight circus and her uneasy relationship with fame in an upcoming interview with Allure magazine.

The actress reveals that when she took on the role of Bella Swan in the vampire saga, she had no idea it would become a full-time job.

“What people told me (when I signed on to Twilight) was that there would be a lot of fan girls, people who love the books,” she says.

“But people don’t tell you that as long as you’re living in Los Angeles, it’s a show every second of your day. It’s like the Kristen show. And it’s so boring!”

Kristen concedes that her discomfort in the spotlight may have been misunderstood as dismissiveness towards the franchise that has made her an international star.

“I spend so much of my time guarding against sounding insincere about something that I would die for,” she adds.

“Maybe I’m overcompensating...I care so much. And it gets reported as the opposite.”

As for her refusal to fit neatly into the role of the Hollywood starlet, she says: “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! I never was that girl. It’s not like I was really clean-cut last year.”

Do you applaud Kristen for being...well, just Kristen!
