Charlie SheenLooks like Charlie Sheen's rehab at home is working out for him. TMZ reports that the 'Two and a Half Men' actor passed two drug tests since he began his in-home rehab, one taken on Sunday morning and the other one taken last week.

The troubled 45-year-old is currently being treated by a sober coach who comes to Sheen's multimillion-dollar Los Angeles mansion. "He is at home now, and those close to him are trying to get him to enter a facility," a source said. "But he doesn't think he has a problem."

TMZ also reported that Sheen got a standing ovation last week after he delivered an anti-drug speech to the UCLA baseball team. His advice was simple, "Stay off the crack. Drink a chocolate milk."
