Every day is a holiday for Charlie Sheen, or a holiday party, at the very least. The Two and a Half Men star is up to his old tricks just days after ex-wife Denise Richards shot down rumors that the troubled actor had met his demise in a tragic snow skiing accident. While Richards tried to convince the world that the free-spirited freak was spending the holidays close to home, that couldn't be further from the truth, according to those in the know. While Sheen is apparently alive and well, he's allegedly on a slippery slope - and not of the skiing variation, insiders tell Radaronline.com. That's because the only thing he's powdering these days is his nose. The source tells Radaronline that Sheen celebrated the one-year anniversary of his arrest on domestic violence charges by partying like a rock star. Not on his itinerary was spending time with his family, says the source: "He skipped going to his brother Emilio's, didn't show up at Denise Richards' house and also skipped seeing his daughter Cassandra. He's back partying again. Although it's tough to say he's back partying because he never really quit!" It appears that CBS's token funny man has continued on a downward spiral since his much publicized meltdown in a fancy New York City hotel where he trashed his room and ended up hospitalized. Another insider says that the actor has been on the rails ever since that fateful night with porn star Capri Anderson. The source confides to Radaronline, "He did a lot of cocaine that night. He likes hookers and he likes coke and he's got enough money for both." While the holidays may be a difficult time for some people, it definitely wasn't for the swinging bachelor. The source adds, "He's been having a great time partying like crazy for the past several weeks."
