BEVERLY HILLS, California — When Britney Spears supports a charity, Hollywood comes calling. On Wednesday night, the femme fatale and her family hosted a private event in Beverly Hills that was attended by Kim Kardashian, Selena Gomez, Kellan Lutz, Hilary Duff and others — all in support of the St. Bernard Project. The Louisiana-based nonprofit aims to rebuild homes of those affected by Hurricane Katrina, as well as helping rebuild their lives.

Just a few days before the event, Brit called out to her devoted fanbase via Twitter to support the cause. "Text BRITNEY to UNITED (864833) to donate $10 to the St. Bernard Charity, which is dedicated to rebuilding homes after Katrina," she tweeted.

Once she arrived to the event, all eyes were on Spears as she graced the red carpet in a form-fitting lime green cocktail dress. She looked vibrant, posing for photogs, who snapped away in a frenzy.

Hilary Duff, standing just a few feet down from Britney, couldn't help but take in the action.

"Gosh, I'm such a huge Britney Spears fan, I'm kinda freaking out that she's right over there," Duff told MTV News. "I love the whole 'Toxic' thing, I really like 'Womanizer' — she's just talented all around and I'm a huge fan, excited to be here. And she keeps it going, you know, like all of her new songs are just as good as the last, and I'm impressed by her career.

"I've actually met her a few times before and she's really sweet, and I'm sure we're gonna be talking about food more than anything tonight," Duff continued.

Once inside, Britney wasn't the only Spears spreading Southern hospitality: Her dad, Jamie, was manning the kitchen. Guests were treated to a Southern-style sit-down dinner with all the fixin's.

Of course, it wouldn't have been a proper Southern meal without some sweet tea, and guests sipped on the pop princess' special recipe of lemon and peach tea.

Britney serves as an ambassador of the St. Bernard Project, whose volunteers number around 32,000. Together, they've rebuilt homes in the New Orleans area for 350 families and counting.
