Jessica Marie Alba (born April 28, 1981) is an American actress whose TV and film credits include Dark Angel, Honey, Sin City, Fantastic Four, Into the Blue, Idle Hands and 2007's Good Luck Chuck. Alba rose to prominence following the television series Dark Angel, then expanding her réméo film, predominantly within the confines of action and comedy. Alba appears frequently on the "Hot 100" section of Maxim, and was voted AskMen.com's No. 1 on their list of "99 Most Desirable Women" in 2006, as well as "Sexiest Woman in the World" in FHM in 2007.

Alba was born in Pomona, California, the daughter of Catherine (néJensen), who is Danish American on her father's side and French American on her mother's side, and Mark Alba, who is Mexican American (though both of his parents were born in California). Alba's parents married while in their teenage years. Her maternal grandfather was a Marine NCO for 30 years, serving in the Pacific during WWII, and later as Asst. Drum Major for the United States Marine Band. Alba was raised in an Air Force family, along with her brother, Joshua and her grandparents, until she was seventeen years old. 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 ruptured appendix, and a cyst on her tonsils. This isolated 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.

She has also acknowledged suffering from obsessive-compulsive disorder during childhood. Her health improved, however, when her family moved to California. She graduated from high school at age 16, and subsequently attended the Atlantic Theater Company.

In 2006, readers of Askmen.com voted Alba No. 1 on 99 Most Desirable Women, while in 2007, Maxim Magazine placed Alba on the number 2 spot of their "Top 100", after Lindsay Lohan. Both GQ and In Style had Alba on their June covers, and in May, after eight million votes, FHM (UK and USA editions) named Alba the winner as "2007.s Sexiest Woman in the World".

Alba has received successful public reception in popular culture. In 2001 Alba received a Teen Choice Award for Choice Actress for her role in Dark Angel. In 2003, 2004, 2005, 2006, and 2007, Alba appeared on Maxim's Hot 100 list. In 2006, Alba received an MTV Movie Award for "Sexiest Performance" for Sin City. In 2007, Alba received the Spike TV Guys' Choice Award for "Hottest Jessica".

On the cover of the March 2006 issue, Playboy magazine named Alba among its 25 Sexiest Celebrities, and the Sex Star of the Year. Alba was involved in litigation against Playboy for its use of her image (from a promotional shot for Into the Blue) without her consent, which she contends gave the appearance that she was featured in the issue in a "nude pictorial". However, she later dropped the lawsuit after receiving a personal apology from Playboy owner Hugh Hefner, who agreed to make donations to two charities that Alba has supported.

Alba fears being typecast as a sex kitten based on the bulk of parts offered to her. "Somehow, I don't think this is happening to Natalie Portman," laments Alba. In the interview, Alba says she wants to be taken seriously as an actress but believes she needs to do movies that she would otherwise not be interested in to build her career, stating that eventually she hopes to be more selective in her film projects.
