Actor Charlie Sheen has been ordered to serve 30 days at a Malibu rehab under a no-jail plea bargain after the actor pleaded guilty to assaulting wife Brooke Mueller.

The deal caps a headline-grabbing saga that exploded with Sheen”s Christmas Day arrest on suspicion that he pinned wife Mueller, 32, to a bed and held a knife to her throat during an Aspen family vacation.

Sheen, who appeared in Aspen court to enter the plea, also must serve three months” probation and show proof that he”s completed 36 hours of counselling.

In exchange, prosecutors dropped felony menacing and criminal mischief charges.

The “Two and a Half Men” star will fulfill the rehab requirement at celebrity-friendly Promises, the same rehab he checked into earlier this year, his lawyer said.

“The fact that the DA”s office is allowing Charlie to do his sentence at Promises as opposed to jail is indicative of the strength of their case. This is great resolution for us,” the New York Daily News quoted attorney Yale Galanter as telling the News.

He and Mueller signed preliminary divorce paperwork earlier this year and are expected to file with the court now that the criminal case is resolved, TMZ.com reported.
