It's a sad day for Anger Management actor Charlie Sheen. One of Sheen's closest friends and on-again/off-again personal assistant Rick Calamaro was found dead this week. According to TMZ, the body of the 46-year-old club promoter was discovered by police in his Los Angeles apartment, surrounded by drugs and alcohol. One law enforcement source tells TMZ that "numerous pain medications and an open bottle of alcohol" were by Calamaro. Even sadder, it appears Calamaro had been dead for days. TMZ adds that Calamaro was with the former Two and a Half Men star back in 2011 when he destroyed his hotel room at The Plaza Hotel and got into a dispute with porn star Capri Anderson. Many people blamed Calamaro for supposedly plying the recovering addict with drugs. So far, police have yet to issue a cause of death. Sheen hasn't commented on the death of his close pal.
