KATE'S FINAL FLING
Bride gone wild! Grey's Anatomy's KATE WALSH
hit Vegas Aug. 4 for a fun and flirty bachelorette party. She and former costar SARA RAMIREZ—along with a gaggle of gals—began the day lounging poolside in a private cabana at Tao Beach. But when Walsh (who got engaged to television exec ALEX YOUNG in May and will star in the spinoff Private Practice
this fall) returned to her room, she found two male McStrippers waiting. Next up? A dinner of sushi, lobster wontons and Kobe beef at Tao Bistro—where Ramirez kept things sizzling. "Sara got on the table and started dancing," says the source. "Everyone was laughing and Kate couldn't stop smiling." Moving on to Tao Nightclub, Walsh showed off her own moves on the club's catwalk until 1:30 a.m. Meow!
ZAC EFRON was shopping in an N.Y.C. Gap Aug. 4 when a 7-year-old girl recognized the teen idol. Still, her mom wasn't quite convinced, asking the High School Musical
cutie, "What's your name?" The actor responded, "Zac," with a quick wink to his pint-size fan ... who promptly burst into tears.
It was an O.C. reunion Aug. 4, when BEN McKENZIE and ADAM BRODY boogied on the dance floor at Playboy's annual Midsummer Night's Dream party.
and RICK FOX are reuniting—onscreen at least. The ex-NBA star will join his ex-wife for two or more episodes of Ugly Betty this fall. "He'll be playing Dwayne, her bodyguard," a source tells Insider. "Things get heated."
