Jessica Alba, Party Mom

Jessica Alba certainly seems to be settling into maturity since giving birth to daughter Honor Marie Warren on June 7.

Sure, the former Dark Angel star was spotted making the Hollywood party scene on Sunday.

But it was during the day. With her baby and husband, Cash Warren. And it was a children’s party, where the wildest thing to occur would be a piñata mishap.

Alba, 27, was decked out a lot less glamorously than usual, sporting a heavy jacket and white-framed sunglasses that might have been on loan from Borat’s kid.

Was the dressed-down, bundled-up ensemble due to Los Angeles’ cold snap this weekend, or is Alba just experiencing a frumpy streak lately?

At least Alba had some glamorous show-biz company.  Also attending the event were 27-year-old Nicole Richie and Joel Madden, 29, with their daughter Harlow, who turns one year old on January 11—coincidentally, a day after Cash turns 29.

Did Honor and Harlow have a cute contest?

Someone alert the SWAT team; things could get rowdy!
