Adler admitted, though, that Barton gets a little jealous when he's onstage – often shirtless: "She doesn't like all the girls screaming at my naked body." But it must have made her feel better when he whisked her off to Paris for her 20th birthday. "Not a lot of planning – we fly by night," he says. "Paris is one of the most beautiful cities I've seen in my life. It is that romantic cliché." Still, he hasn't proposed: "Rumors!"
One Night in the Club ...On a recent Saturday night at the L.A. club Privilege, Jessica Simpson, pal CaCee Cobb and hairstylist Ken Paves arrived so late (12:55 a.m.!) they couldn't wrangle a front-of-the-room VIP table. No such bad luck for Nicky Hilton and boyfriend Kevin Connelly, who sat with Wilmer Valderrama and engaged in an ice-throwing match with a neighboring table. Meanwhile, Will.I.Am (Black Eyed Peas) cracked open bottles of Cristal at his dance-floor table as Paris Latsis hosted the Pussycat Dolls at his. Also there that night: Mary-Kate Olsen (who got a table), Serena Williams and Tara Reid.
Caught in the Act Matthew Fox, at the Hard Rock Hotel & Casino in Las Vegas, watching (and celebrating) the Pittsburgh Steelers' Super Bowl victory. The Lost star had bet on the winning team.
Bruce Willis, at club Butter in New York City, dancing on a banquette to a Michael Jackson medley. Also there, at separate tables: Giovanni Ribisi and Dennis Rodman.
