Jessica Biel finds dealing with the paparazzi the hardest part of the celebrity lifestyle - insisting the ever-present photographers often drive her to tears.
The actress found herself a major media target when she began dating pop star Justin Timberlake in 2007.
And the 26-year-old admits that she is often left terrified by her encounters with the paparazzi.
She tells Britain's Marie Claire magazine, "It's hard. The hardest part of this whole wonderful, bizarre lifestyle and profession.
"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 c**p 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?'"
