Grab a jacket -- hell might just be freezing over. Troubled addict Brooke Mueller just wrapped up a whole three months of rehab at the Cirque Lodge in Utah. The 34-year-old cocaine addict managed to complete an entire stint at the facility without bailing or bingeing. The timing couldn't be better because the mother of two is set to go before a judge in a few weeks on assault and cocaine possession charges stemming from an arrest from this past December. Although the blonde beauty has tried -- and failed -- at rehab too many times to count, Mueller's rep Steve Honing tells Radaronline.com this time is the real deal. Says Honing: "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." One source maintains that Mueller is determined to stay straight for the sake of her sons. Says the insider, "Brooke finally recognized that she needed to surrender to the disease, and admit she was powerless to it. Her previous rehab stays weren't long term, and she didn't stay overnight and would go home at the end of the day. What it came down to was Brooke couldn't be calling the shots about how she was going to be treated. She needed long-term residential treatment, and she got it. Brooke is very hopeful for her future and wants to focus on her recovery and sobriety and being the best mom she can be to her twin toddler sons." Barring any appearances at local pawn shops or street corners, it's safe to say that Mueller is definitely headed in the right direction.
