Actress Kristen Stewart is scared that her fame might lead to someone killing her one day.
She fears someone will log on to a social networking site to find out her location, then travel to where she is and murder her, reports contactmusic.com
In an extract from new e-book Robert Pattinson, Kristen Stewart, Taylor Lautner - In Their Own Words by Talia Soghomonian, Stewart told interviewer Sian Edwards: "Nowadays it's harder because everyone is on Facebook and everyone knows where you are all the time, and everyone's twittering."
"Like I'm going to die because somebody is going to say where I am and somebody is going to kill me. Someone's going to twitter my location and then it's going to be like, boom."
However, she admits the communication possibilities on the social networking sites are "really great".
"I actually think too much of anything can be scary, but at the same time it's also an opportunity. I mean mass communication is a good thing. It's actually a really great thing, it's just scary," said the actress.
