Brooke Mueller sober house sweats sneakers

Brooke Mueller has been undergoing voluntary treatment at a sober living facility as an outpatient, in light of recent accusations of drug abuse made by ex-hubby Charlie Sheen.

Brooke took it upon herself to check into the facility, which looks like an incredibly huge mansion, and we're happy to see her looking fit and healthy in light of all she's been through lately.

After an intense few weeks battling it out over custody of their two-year-old twins Max and Bob, Mueller and Sheen have finally agreed on a custody deal. Part of that deal requires both parents undergo regular drug testing, which is why Mueller enrolled in the program; Sheen's ex wants to prove she's drug free and is making an effort to keep it way.

Mueller also recently dropped her request for an extended restraining order against her ex-hubby. We're glad things are finally going a bit smoother for the pair!
