Jessica Alba was out and about in LA, heading to a spa to pamper herself for her birthday on Thursday. The actress turned the big 3-0 and we celebrated with Jessica Alba's hottest bikini pictures through the years. She also fielded lots of well wishes from her Twitter friends. It's already been a big 2011 for the sexy star, who is expecting her second child with Cash Warren. She's been focusing on her young family lately, spending lots of time with her husband and her daughter Honor, and joining them for playdates at the park and trips to the grocery store. She also took a quick girls' trip to China with friends last month, and stopped by a nail salon after dropping Honor off at school earlier this week.
