Jessica Marie Alba (born April 28, 1981) is an American actress. She is best known for her roles in Dark Angel, Sin City, Fantastic Four and Into the Blue.

She became famous after big-screen roles in Never Been Kissed and Idle Hands, Jessica Alba became the first "It" girl of the century as the title role in James Cameron's sci-fi TV series, Dark Angel. Back from a short hiatus, she starred in the hip-hop dance flick Honey in 2003 and the star-studded Sin City in 2005.

Jessica Alba was born in Pomona, California to Mark Alba, who is of Mexican descent, and Cathy Jensen, who has Danish and French-Canadian ancestry. Her maternal grandfather was a 30-yr Marine noncom, serving in Pacific during WWII, and later as Asst. Drum Major, USMC Band. Alba was raised in an Air Force family, along with her brother, Joshua Alba, and her grandparents until she was 17. Her father's Air Force career took the family to Biloxi, Mississippi, and Del Rio, Texas, before they settled back in California. Alba's early life was marked by a multitude of physical maladies; she suffered collapsed lungs twice, had pneumonia 4-5 times a year, a burst appendix, a cyst on her tonsils and asthma. She has also acknowledged suffering from obsessive-compulsive disorder during childhood .

This served to isolate her from other children at school because, as she claims, she was in the hospital so often that no one knew her well enough to befriend her. Her health improved, however, when her family moved to California. Alba had expressed interest in acting since the age of five. She took her first acting class at age twelve, and an acting agent signed her nine months later.

Jessica had the looks to make us believe she was a genetically-enhanced woman in the sci-fi hit Dark Angel, and has the body to make any guy want to go see a chick flick like Honey. Even though she's been away from the spotlight for a few years, Jessica has always been on our minds.
