Many of you will wake up tomorrow and woozily resolve to be better behaved in 2013. We're here to strongly discourage that. See, life is just more interesting when you let things get debaucherous. You could canoodle with a comely nude stranger (Prince Harry), wear an Olympic medal (Naomi Campbell), or find a kitten (Demi Moore). Sure, there are potential pitfalls, like bruises (Pierre Casiraghi), lost shoes (Tara Reid), and the occasional lawsuit (Vladimir Restoin-Roitfeld), but the battle scars are probably worth it. Enjoy our roundup of the year's top celebrity partiers; may we all have as much fun in 2013 as they did in 2012. Happy New Year's Eve, everyone!
