Brooke Mueller has voluntarily entered a rehab for a reported addiction to Adderall, making it her 19th time seeking help at a treatment facility for substance abuse.

Charlie Sheen's ex-wife was hospitalized last week for an alleged drug overdose on the psycho-stimulant. At the time, Mueller maintained that the housekeeper overreacted by calling ambulances, claiming she was simply napping rather than being "unresponsive," but this week her attorney set the record straight.

"Brooke was uncomfortable with the way Adderall was making her behave," attorney Yale Galanter told TMZ about his client's decision to seek help.

"Brooke continues her lifelong battle with drug addiction by taking these steps to prevent a further drug relapse," he added.

Get well soon Brooke!
