Brooke Mueller

Charlie Sheen's ex-wife, Brooke Mueller, is receiving at-home rehab treatment more than a week after being arrested on charges of felony cocaine possession with the intention to distribute, Us Weekly reports.

"Recognizing past attempts at treatment have not been successful, Brooke has decided to take a different approach to deal with her addiction," Mueller's spokesman, Steve Honig, tells the magazine. "Brooke will be participating in a program during the day, and will be under expert supervision 24 hours a day, seven days a week. In addition, Brooke has requested to be tested on a daily basis for cocaine and other illegal substances so there is no doubt as to her commitment."

"Brooke will retain custody of her children, both of whom will continue to remain at her home and be cared for by Brooke and their longtime nanny," Honig also told Us Weekly. "Charlie and Brooke's family are all fully supportive of this decision and recognize the importance of maintaining the children's normal routine."

Mueller, 34, was previously arrested on charges of cocaine possession in March 2001, but the charges were later dropped. She has been in rehab twice within the past year and as recently as July.

Mueller and Sheen married in May 2008 and Mueller gave birth to twin sons Bob and Max the following March. She filed for divorce in November 2010, almost a year after Sheen was arrested for assaulting Mueller in their Aspen, Colo. home on Christmas Day. (He later pleaded guilty to misdemeanor assault as part of a plea deal).
