Although she's the female lead in the Twilight franchise (last year, the first film grossed nearly $400 million worldwide), Kristen Stewart doesn't emulate other blockbuster actresses -- not even Brad Pitt's girl.

"I don't want to be a movie star like Angelina Jolie," Stewart tells BlackBook magazine.

"Nothing about being a celebrity is desirable," the 19 year-old insists. "I'm an actor. It's bizarre to me that everybody's so obsessive."

One topic of obsession: her relationship with onscreen lover Robert Pattinson, 23. Pattinson recently told Vanity Fair that, despite intense speculation otherwise, they are simply "good friends," and that he considers her "the best young actress around."

But Stewart made a thoughtful observation about Edward Cullen, Pattinson's Twilight character.

"Edward is actually a really good parallel to fame," she muses. "As a vampire, he has a sad, desolate life -- fame is the same."

 The Twilight Saga: New Moon premieres Nov. 20. Production on the third installment, The Twilight Saga: Eclipse, wrapped last week.
