Can you believe Jessica Alba started kicking ass in Dark Angel 14 years ago? Believe it! Jessica has been one of the sexiest stars for over a decade and will be resuming her role as exotic dancer Nancy in Sin City: A Dame To Kill this Friday. It's been nine years since the first film, but Alba still has one of the most banging bodies around.

In addition to acting, Alba founded The Honest Company to make sustainable products for family and the home — focusing on natural ingredients that make you look and feel beautiful. The mother of two has always been a bit of a fashionista, from looking effortlessly cool in a pair of jeans and sheer top to rocking a sexy mermaid gown on the red carpet. But her most dramatic changes over the years has always been to her hair. Whether it's black, blonde, wavy, or sleek, we think Jessica looks gorgeous no matter what she does. Work it, girl!

Check out the Sin City star's style evolution in the gallery above.
