Alba refused to strip for 'Sin City 2'?

Actress Jessica Alba reportedly refused to strip for "Sin City 2" because she isn't happy with how she looks after giving birth to two children.

The actress, who has two daughters Honor Marie and Haven Garner, is said to have used body double to shoot for 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, reports contactmusic.com.

"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,'' the source added.
