The 29-year-old, who hit the headlines last year when she appeared to have gained a few pounds, is starring in a new show - Jessica Simpson's The Price Of Beauty - which examines people's efforts to measure up their society's standard of beauty.
Jessica said: "You can't walk anywhere without thinking, 'I wonder if they think I'm fat .... I wonder if they've read that story, I couldn't help it - and I think that once I realised it wasn't going to stop, I had to find a way to accept it, and I had to find a way to use it."
Jessica and her friends meet a woman in Thailand who burned herself permanently from bleaching her skin lighter, and they talk with a former Paris model who starved herself to under 100 pounds to be thin.
"I'm very vulnerable on the show. I'm very open. I don't have anything to hide," Jessica said. "I want people to know I am just a normal girl that faces normal issues just like everyone else."
