The Mercury Lounge's Halloween party is your chance to live out the best and worst of the year's celebrity news. Dress as your favorite Tinseltown screwups to win cash and prizes at the Hollywood Rehab Theme Party. Competition will be tough, so here's our tip: It's way too obvious and easy to dress up like Lindsay Lohan, Owen Wilson, or Paris Hilton, with bad makeup, head bandages, and a conspicuous dusting of white powder. But shaving your head like a bald Britney? That shows commitment. Skin to win!
