Jessica Alba has insisted on a body double for her stripping scenes in Sin City 2.
The actress isn't happy with her body after two kids and has insisted on having a stand-in for her more provocative scenes.
"She was crushed when filming began and she didn't have her original body back, so she told producers she wanted a body double," a source told Life and Style magazine.
"Her body is incredible, but for her it's not good enough.
"She's cut out carbs and does the P90X Ab Ripper twice a day, but she still isn't happy."
Jessica, 31, has also reportedly been chain smoking to keep her mind off food.
"She's been chain smoking lately to keep her appetite at bay," the insider added.
"Jessica struggled with an eating disorder in her teens and when she's under pressure to look good for a part, she can slip back into extreme behaviour."
