(digitalspy.co.uk) - Jessica Biel has admitted that she considers quitting the movie industry because she is frightened of the paparazzi.The 26-year-old actress, who is dating Justin Timberlake, revealed that the constant intrusion from snappers is the most difficult aspect of her job."It's hard. The hardest part of this whole wonderful, bizarre lifestyle and profession," Biel told Marie Claire magazine. "You have to be Zen about it, because it can make you crazy."There are times when I have been followed by men with giant cameras in giant SUVs all day long. It scares the crap out of me and I literally come home and emotionally erupt and cry it out and sit on the floor and think: 'Do I really want this?'."Timberlake's former 'N Sync bandmate Lance Bass recently predicted that he would settle down with Biel "pretty soon".
