Kristen Stewart's friends are "plagued" by her fans on the internet.

The 'Twilight Saga' actress - who shot to global fame after appearing alongside her rumoured boyfriend, Robert Pattinson in the vampire film franchise - admits her close pals and family members complain to her about the number of people attempting to contact her through social networking websites.

She said: "My friends all have Facebook pages and stuff because they are normal people that can have those things. But they are constantly being plagued because they somehow find out I'm friends with them and then the imposters try to go on and message my brother pretending they are me. My brother and my friends always complain to me about it."

The 20-year-old starlet recently admitted she felt lucky to have been supported by her family during her rise to fame.

She cites her loved-ones as the reason why she didn't go off the rails like some of her famous peers.

She said: "My family are amazing. I had, like, the perfect upbringing. It sucks for people like Lindsay Lohan, but it's not her fault that she's so off the rails - and she's smart, very smart."
