To put it lightly, Jessica Alba was less than pleased when she finally turned 30.

"I was pretty p*ssed off. I dont know why it was so hard, it just was," the mom of two told Marie Claire about turning the big three-oh.

The actress, whom we just snapped arriving at LAX last night after promoting Sin City: A Dame To Kill For in NYC, added that instead of having a big blow out -- she had to keep it tame because she was with child at the time. "I was pregnant [with Haven] first of all, and I really wanted to party like a rock star. I didnt even know I cared about my twenties until I turned 30."

But luckily, the 33-year-old has settled into her age and is realizing she's more comfortable in her skin than she was before.

"I feel like I look better now. I think I came into my own physically in my thirties, even when I'd had kids. I'm actually smaller now because everything kind of hangs off differently. But I feel more like a woman, with not such a girl face. I had such chubby cheeks," she told the mag.

In the interview, she talked about her relationship with producer Cash Warren, whom she wed in 2008. "Immediately we felt like really close friends. I dont know if that translates into being swept off your feet, as it wasnt really that; it was more, 'Im going to this person for the rest of my life because he feels like family already.' And that was even before we started dating," said the stunning star.
