{babes} Stewart fears red carpet assassination

Kristen Stewart frequently fights back tears on the red carpet - because she's terrified she will be "assassinated".

The actress has found herself thrust into the spotlight at movie premieres since she shot to fame starring opposite Robert Pattinson in the Twilight films.

But she has confessed she finds red carpet events upsetting because she is convinced a crazed fan will "turn" on her.

Stewart tells Britain's Hello! magazine, "I don't feel very comfortable on the red carpet. Sometimes I get really excited for what I'm going to and then try to take good pictures and go inside...I literally have to keep myself from crying sometimes.

"I look out there at a thousand people and I realize they could rush me and assassinate me. No security could protect me. Ostensibly they're fans, but I think about them turning on me."
