Lance Bass, taking the party back to his place, after hanging out at New York's Splash Bar with a bevy of hot guys. Earlier, the former 'N Sync member – dressed in a floral print button-down shirt, jeans and boots – danced in a booth next to the downstairs bar. He also flirted with a "brunette beefcake," a fellow partier tells us.
Rihanna, passing the time before her flight at Newark Liberty International Airport by playing around on a laptop, and laughing with her entourage and dog. The singer, dressed in a cream-colored cardigan with a big collar, belt and knee-length denim skirt, seemed to be in good spirits, but she wasn't in the mood to sign autographs.
Russell Simmons, pleasantly chatting with fellow classmates as he waited for his morning yoga class at Maha Yoga in Brentwood, Calif.
Top Chef champ Hung Huyng, continuing his victory celebration by dining with show host Padma Lakshmi at Chicago eatery Rockit Bar & Grill on Thursday night. And he wasn't alone: The winner was joined by his castmates and judge Tom Colicchio. And a few tables over: DJ AM dined with some friends.
