Charlie Sheen's ex-wife, Brooke Mueller, began a outpatient drug treatment program in December 2011, more than a week after a cocaine-related arrest and will retain custody of her and the actor's twin sons.
Mueller has been in and out of rehab in recent years to combat substance abuse, as has Sheen.
'Recognizing past attempts at treatment have not been successful, Brooke has decided to take a different approach to deal with her addiction,' her spokesperson said in a statement to OnTheRedCarpet.com.
Mueller was released from an intensive three-month rehabilitation program in February 2012 and will continue treatment for her drug and substance abuse problems, according to her rep. She was charged with felony cocaine possession with intent to distribute and assault, stemming from her December arrest.
