**Justin Timberlake may be in fashion mode, but that didn’t stop him from jumping into the deejay booth at the W Hotels Lounge for an impromptu remix of “SexyBack.” He told staffers there that he and gal pal Jessica Biel are staying at the W Union Square this week. The two were spotted canoodling at a private table at the Rast after-party at Rose Bar, where they and a few friends put a serious dent in a bottle of top-shelf tequila. The party was one in a string of successful Fashion Week soirees organized by Rose Bar’s creative director, Nur Khan. Justin’s mom, Lynn Harless, didn’t miss out, and her cowboy hat was still bopping tableside long after Buzz called it a night. “These are our roots,” Mom said, tapping her hat. “We are from Tennessee, and I’m proud to wear this.” (Click here for the Review and Photos of William Rast)
**Give yourself a cookie if you guessed “world peace” was Paris Hilton’s answer when Buzz asked what she wanted for her 28th birthday yesterday.
**Moby seems to have wised up since his run-in with Eminem a few years back. “I’ve learned, in the future, never pick feuds with successful musicians whose friends carry guns,” he told Buzz at alice + olivia’s Bryant Park store.
**No matter how hip-hop you may be, sagging doesn’t go over so well in the tents. Common learned that lesson before yesterday’s Diesel show, when his manager offered him a belt to lift up his drooping Diesel jeans.
**Kate Bosworth agreed to only a few interviews yesterday in the W Hotels Lounge. Did playing Lois Lane in “Superman Returns” make her weary of journalists? “I think it made me aware that there is always an agenda involved.” Buzz has no comment.
**Club “kids” Richie Rich, Kenny Kenny and Patrick McDonald enjoyed Monday night with an intimate dinner – in the front window of the Fifth Avenue Diesel store. “It feels like a Michael Alig party,” remarked Kenny Kenny, presumably referring to bashes the party monster threw at Limelight rather than his current shindigs in prison.
**Tim Gunn never quite got over “the sorrow that I felt when I put my dear family dogs to sleep,” he told Buzz yesterday after a screening of a PETA documentary that he narrated. That’s why, “On ‘Project Runway,’ fur is not permitted in final collections at all.”
**Taking a cue from other athletes who have made the leap from field to runway, NY Jet Darrelle Revis told Buzz he is launching his own T-shirt line called Loco S Star. Thing is, runway shows are a little boring compared to the thrill of the game. “It’s a good thing they keep them short,” Revis said. “But maybe they should have a singer perform before the show. Or maybe a stand-up comic.” – Additional reporting by Maureen Callahan and Brian Niemietz
