Kristen Stewart - Kristen Stewart's Vampire Life

Kristen Stewart said being famous is "sad and desolate" like being a vampire.

The 'Twilight' actress said Edward Cullen - the vampire her alter ego Bella Swan falls in love with in the film series – gives a handy parallel with what It's like being famous.

Kristen, 19, said "Edward is actually a really good parallel for fame.

"As a vampire he has a sad, desolate life – fame is the same."

She also talked about how she doesn't understand the cult of celebrity, and is keen to avoid it all costs, so she is taken seriously as an actress.

She added: "I don't want to be a movie star like Angelina Jolie. Nothing about being a celebrity is desirable.

"I'm an actor, its bizarre to me that everybody's so obsessive."

Kirsten did, however, say she relates to her character's actions in the second instalment of the films series, 'New Moon', more since the break up of her relationship with boyfriend Michael Anagrano earlier this year.

She added: "The worst thing about a break-up is not losing someone, but being told you're wrong.

"You don't trust yourself anymore. In the first movie Bella unabashedly followed her guy. Then in the second one she's like, 'I don't know why I've done this because it's been wrong,' and that I can relate to."

'Twilight: New Moon' is released in cinemas later this month.
