Brooke Mueller has completed her stay in rehab and is back in Los Angeles, her rep confirms to RumorFix.

The 34-year-old was in treatment at the Cirque Lodge in Sundance, Utah after being arrested last December for assault and drug charges in Aspen.

Brooke’s rep says: “After successfully completing an intensive three-month drug and alcohol treatment program, Brooke returned to Los Angeles yesterday and has immediately begun an aggressive outpatient program that includes a sober companion."

"Brooke is feeling better than ever before, and is committed to continuing treatment for as long as necessary to maintain her total and complete sobriety.”
