Who's the latest celeb to hit Broadway's homage to L.A.'s Sunset Strip? How about Hollywood star Vince Vaughn? The fast-talking funnyman of flicks like Old School, Dodgeball, The Wedding Crashers and the current Couples Retreat paired headed to Rock of Ages on October 9 for an evening of high camp humor and classic hair band tunes. After the final bow, Vaughn zipped backstage as quickly as he fires barbs on screen, hugged it out with cast members including newcomers Kerry Butler and Tom Lenk, Constantine Maroulis and longtime scene-stealers like Mitch Jarvis and Lauren Molina, then slipped out the stage door to continue his rockin' night in the Big Apple. We managed to snap a pair of pics before he dashed off. Click here to catch Vince on Broadway.
