Shortly after flying to Aspen for the arraignment of husband Charlie Sheen, Brooke Mueller has checked herself in the rehab for substance abuse. Mueller has been checked into a California rehab facility since last week and her lawyer has just confirmed that she is there. Sources report that just hours before checking herself into the facility, she was out partying with Charlie. This latest report follows the whirlwind few months that started Christmas Day when the couple were embroiled in a fight which landed Sheen behind bars and Mueller alleging that Sheen threatened her with a knife. Mueller was then hospitalized for pneumonia then checked into a North Carolina Wellness Program for—not addiction and now is in rehab, rehab to deal with substance abuse problems. That’s a lot to keep up with.
