Kristen Stewart thinks she's lucky not to be like Lindsay Lohan.

The 'Twilight Saga' actress is pleased to have had the support of her family during her rise to fame, and admits it is easy for young stars to lose their way in life.

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."

'Mean Girls' actress Lindsay, 23, has had a turbulent few years as she battled problems with drink and drugs.

Although Kristen is thrilled she has remained level-headed, she hates the intrusion into her life and believes it is similar to "rape".

She told Britain's Elle magazine: "What you don't see are the cameras shoved in my face and the bizarre intrusive questions being asked, or the people falling over themselves, screaming and taunting to get a reaction. The photos are so... I feel like I'm looking at someone being raped. A lot of the time I can't handle it."

Since she first appeared in the 'Twilight' movies, Kristen and her hunky co-star Robert Pattinson have been continually questioned about the status of their relationship.

However, the 20-year-old starlet has vowed to remain secretive on the subject.

She added: "What I say is that why would I want anything that's private to become entertainment for other people?"
