Charlie Sheen Enters Rehab

'Two and a Half Men' halts production.

Charlie Sheen has entered rehab "as a preventative measure," according to a statement issued Tuesday (February 23) by his publicist, which avoided any further specifics about the actor's treatment.

Subsequently, CBS (whose parent company, Viacom, is the same as MTV's) announced a temporary halt to production of the highly rated sitcom "Two and a Half Men" until Sheen is ready to return to work.

"CBS, Warner Bros. Television and [Executive Producer] Chuck Lorre support Charlie Sheen in his decision today to begin voluntary inpatient care at a treatment center," the statement reads. "We wish him nothing but the best as he deals with this personal matter."

Celebrity Rehab Repeaters

The 44-year-old actor, best known for roles in films like "Platoon" (1986) and "Wall Street" (1987), made headlines about two months ago when he was charged with felony menacing and misdemeanor charges of third-degree assault and criminal mischief after an argument with his wife, Brooke Mueller, at their Aspen, Colorado, home.

A representative for Mueller told The Associated Press that the 29-year-old is in rehab herself, also for undisclosed reasons. TMZ reported that she's receiving specialized rehab-style treatment at a private home in Los Angeles, where the couple's 11-month-old twin boys are staying with her, nannies and a counselor.

This is not the actor's first stay in a rehabilitation facility. Sheen voluntarily checked himself into drug and alcohol rehab for "exhaustion" in 1990. Eight years later, he was back in rehab after heavy drug and alcohol use put him in the hospital.
