Jessica Alba  turns 33 on Monday, and we're celebration 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. Plus, she shows off plenty of PDA with husband Cash Warren on their many trips to St. Barts and Hawaii — we're not sure if their kisses or her many scorching bikini moments are hotter!
