Jessica Alba Bikini Pictures

Jessica Alba turns 32 on Sunday, and we're getting a head start on celebrations with a look back at her best bikini pictures. Jessica's been no stranger to the two-piece and looks equally as fantastic in a swimsuit on screen as she does while lounging on the beach. The actress even rocked a bikini just four months after giving birth to her daughter Honor in 2008, and continues to flaunt her tan and toned body after having daughter Haven in 2011.
