KELLY SAWYER PATRICOF, JESSICA ALBA & NORAH WEINSTEIN

"I’ve met many of the families that are affected [by Baby2Baby] by just being in unfavorable circumstances for one reason or another. I just know how hard it is to raise a kid with all the means that we have. I couldn’t imagine having to choose between a diaper or food for your family that week, or not being able to provide a safe place for your baby to sleep at night, or giving your child shoes that fit for them to go to school," Alba, pictured with the Baby2Baby's co-presidents at the Saturday night gala at 3Labs in L.A., told PEOPLE. "Those types of things are real things that people, right here in L.A., are having deal with, and across the country. So we do everything we can to provide those basic essentials."

Biel — whose restaurant Au Fudge provided some late-night snacks for guests — also took the stage to encourage fellow attendees to give.

We have so much to be grateful for," she said to the crowd.

BUSY PHILIPPS

"I’ve been involved for over six years with the charity, spending time with a lot of the families and the moms that are being served by Baby2Baby, they’re our people," Philipps told PEOPLE on the red carpet. "You know they’re people. There’s nothing that separates me from them except for luck, where you’re born, what you’re born into. Their kids are vibrant and amazing, and they’re just doing the best for their families that they can. So obviously, to be able to help is incredible."

KELLY ROWLAND

"When Harvey happened I remember calling [Baby2Baby co-president Kelly Sawyer Patricof] and saying, ‘What are we doing? How fast can we do it?’ She was like, ‘Oh we’re already on top of it. We’ve already shipped the diapers out. We’ve already shipped the necessities.’ It was not even a thought, as soon as they saw it coming they were all getting ready, they were getting the trucks ready," Rowland told PEOPLE of the organization. "That made me so proud. The same thing happens with any natural disaster — Baby2Baby is always wanting to be first to make sure that they’re there on the spot to help out. It’s just awesome to be a part of."

JULIE BOWEN

"They’ve grown in their mission," Bowen said of Baby2Baby, "but to have started as a grassroots thing where you’re taking, what, gently used stuff that everybody has and no longer needs, and making sure it’s not just going into some dump somewhere, but going very much to families in need; people just coming out of a hospital with no safe place to put a baby. That’s wonderful, that just makes sense, it’s just common sense and it’s great."
