Jessica Alba

Svelte star Jessica Alba didn’t look like the typical new mom at the Keep A Child Alive 5th Annual Black Ball Thursday, but all she could talk about was her 5-month-old daughter, Honor Marie.

“Everything is cute, everything is fun,” the actress said, “including the explosive diarrhea – the best ever.”

Alba says that life with Honor Marie has brought her and husband Cash Warren closer. “It brings family together. It brings friends together. It makes every decision that you make that much more important.”

The next milestone in Honor’s life: her first word. “I think she accidentally says ‘Mama’ when she’s crying,” says Alba. “But I don’t know if it is on purpose yet.”

So is Honor sleeping through the night? “It depends on what you think sleeping through the night is,” says Alba. “She gets a few bottles a night, yes. But she doesn’t wake up and want to hang out.”

Despite her life as a busy new mom, Alba has found time to get back in shape. “I worked out – not for hours, but I definitely had to work out. And I ate, not a lot of sweets and not a lot of cream. I kept a pretty simple organic diet, which I do now anyway.”

All of which puts Alba in a happy place. “She’s the love of my life,” says Alba. “The love is profound. She gives everything more meaning.”
