Twilight star Kristen Stewart has revealed she fears that her fame might lead to someone killing her one day. The actress – who was bombarded with hate messages from fans after cheating on boyfriend Robert Pattinson – fears someone will log on to a social networking site to find out her location, then travel to where she is and murder her. 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,” she added.
