Radar online claims Charlie Sheen’s latest trip to rehab isn’t a “pre-hab” trip at all. Their source tells them Charlie was both boozing and drugging, which was partly behind his wife Brooke’s 911 phone call in which she claimed coked-up Charlie held a knife to her throat and threatened to kill her – a claim she later retracted. “But the partying didn’t stop there. He’s used coke and been drinking many, many other times since then,” the source revealed, claiming Charlie and Brooke did coke together again the night before Brooke went into rehab. TMZ reveals Charlie actually didn’t bother showing up for work for two days before his people realised he was in trouble!PHOTO CREDIT: Warner
