Britney Spears threw a private party last night in Beverly Hills -- and young Hollywood's hottest were all in attendance.

Britney's bash was for the St. Bernard Project, an organization dedicated to rebuilding Louisiana after the devastating Hurricane Katrina. Spears is from Louisiana.

The party, which was attended by guests like Kim Kardashian, Kim's ex-boyfriend Reggie Bush, Kelly Osbourne, Selena Gomez, Shenae Grimes, Kellan Lutz and even Britney's "Crossroads" co-star Taryn Manning, celebrated "Southern Style" -- where attendees snacked on her favorite Southern dishes.

Spears' own father Jamie, who is a professional cook, made some of the cuisine -- with Brit tweeting out a photo of her dad at work. Doesn't he look thrilled:


Britney looked great on the red carpet, wearing a tight bright green dress while posing with boyfriend Jason Trawick.
