London: Actor Charlie Sheen's ex-wife Brooke Mueller has reportedly been instructed by medical professionals to enter a rehabilitation facility for 'at least nine months'. Mueller was recently arrested and charged with assault and intent to distribute drugs after being found in possession of cocaine.

'Brooke has done rehab on her terms in the past. Thirty days isn't enough for an addict like Brooke. Brooke is calling the shots, and not listening to her family, or medical professionals that are telling her she needs to be at an in-patient facility for at least nine months, and not as a day patient, as she has done in the past,' a website quoted a source as saying.

“Anything less than nine months is a disservice to Brooke, and frankly, is a total waste,” the source added.

The 34-year-old last entered a rehab in April this year when she refused to take a drug test.
