Some of Hollywood’s hottest moms came together for the first annual Baby2Baby Gala in Los Angeles this weekend, including Jessica Alba (in Valentino), Modern Family star Julie Bowen (in Naeem Khan), Nicole Richie (in Lorena Sarbu), Rachel Zoe (in Rachel Zoe), and Busy Philipps (in vintage from Decades). “I’m so proud to be part of the work that Baby2Baby is doing,” said Richie, a board member for the non-profit, which was founded by her pals Norah Weinstein and Kelly Sawyer Patricof with the mission to supply families in need with clothing and other necessities for children. The event included both silent and live auctions as well as 299 cased diamond necklaces used as décor. Alba also received the first-ever Baby2Baby Giving Tree Award for her ongoing support of the organization and dedication to families in need in Los Angeles. “I didn’t think twice about joining Baby2Baby,” Alba said during her acceptance speech. “So many kids are going to have a better chance of becoming what they could be because of you guys.” Click through the gallery to see more party photos from this week’s biggest events.
