Natalie Portman and "Top Chef" star Tom Colicchio teamed up with FEED Projects and the FEED Foundation to host a fundraiser to benefit The Hungry in America Project -- a documentary film and multimedia campaign whose mission is to raise awareness about hunger in the U.S.-- at Colicchio & Son's restaurant (Tom's latest New York City venture).

"For the last 25 years as a chef in New York, I've done fundraisers with organizations, such as City Harvest, Meals on Wheels, Share Our Strength and quite frankly, while we're all proud of the work we've done, it's not working," Colicchio, who's wife Lori Silverbush is one of the filmmakers on the project, told StyleList. "Hopefully with this film we can draw attention to the problem by showing what hunger looks like in our country and fix it.

Colicchio was a bit more tight-lipped when it came to where Top Chef 7, which begins shooting in April, will take place. "I can't say."

The evening also marked the launch of the FEED USA Project. "Up to this point we've only supported hunger abroad mainly through the United Nations World Food Programme, so tonight is our launch of the FEED USA campaign, where we start to focus on aiding hungry people in America as well as getting healthier school meals to kids in America," FEED co-founder Lauren Bush, who was wearing a chunky beaded necklace from Monique Pean, explained to StyleList.

Bush, who designs a clothing line called Lauren Pierce, is launching an atelier exclusively at Barneys, where you can design your own dress made of hand-dyed African fabrics from women in the Congo and Rwanda. "I'm definitely saving up for it for spring," her FEED partner Ellen Gustafson told us.

Natalie Portman, in a Dannijo necklace, was excited to try one of Colicchio's vegan specialties. "He does a delicious potato flatbread pizza!," the actress raved to StyleList.

By the looks of the packed house, vying for some of Colicchio and guest chef Rocco di Spirito's scrumptious appetizers, and late arrivers Jake Gyllenhaal and Katie Couric, we have a feeling the Hungry in America documentary will get the funding needed to complete filming.
