Jessica Simpson starving herself?

Pop beauty Jessica Simpson is starving herself.

The star who reportedly turned to food for comfort after her failed marriage and album is currently filming ‘Blonde Ambition’ with Luke Wilson in Louisiana but is not taking advantage of the great food as she is paranoid about gaining weight reports Female First.

During a break from shooting last week, Jessica visited Chili’s restaurant with friends.

One diner revealed to Life and Style Weekly magazine: “She ordered Caribbean chicken salad but she only ate the chicken in it. She left everything else.�

A few days later, homemade gumbo was served on the film set but Jessica passed.

A source on set revealed: “Luke said, ‘This is the best thing ever’. He had his whole face in it! But Jessica didn't touch it.

“She’s not really eating while she’s working because she’s trying to stay slim.�

In November, Tina Fey revealed that Paris Hilton slammed Jessica as a fatty

"Yeah, she wanted to make fun of all the girls she hates. She was like "I want to play Jessica Simpson, I hate her." She would come in the room and say "you should do a show about Jessica Simpson because she's fat."
