Actress Jennifer Aniston is begging photographers to stop hounding her as she worries that someone with more malicious intent may be among them.

The Derailed star was left shocked by the media storm that followed her separation from fellow actor Brad Pitt, and is now becoming exasperated by the continued attention.

She told TeenHollywood: "It's reached an awful level. They really need boundaries and it's a really tricky thing because there are so many people saying, 'You're a public figure, you deserve it, you ask for it'. But nobody asks for that kind of intrusion. I didn't sign any kind of paper saying that is going to come with the job."

The former Friend acknowledged the place of photographers on the red carpet, but revealed that they can create unnerving experiences when intruding into celebrities' personal time.

"You don't know how far they will go. When we show up for a public appearance, we know that that's expected. But when somebody's following you in a car and you don't know if they're a crazy fan with a gun in their hand or they're a paparazzo, that same fear goes through you," Aniston added.
