Happy Birthday, Jessica Alba! The actress, who turns 33 today, has come a long way since her first foray into film in Never Been Kissed, opposite Drew Barrymore. Back then, the young actress was new to the scene, and coming into her own. Alba even joked of her '90s look, saying, "When I first started wearing makeup, I went overboard." Despite finding success in film with hits like Sin City and Fantastic Four, Alba recently took on a different role: launching her own eco-friendly line of baby and home products, The Honest Company, and penning the book, The Honest Life. "Creating this company was something I had to do," Alba exclusively tells InStyle. "We’re completely transparent. All the goods we make are high-performance—and safe—but they’re also beautifully designed, so people will be drawn to them, too."
