Charlie Sheen Ex, Brook Mueller, Suffers Breakdown; In Rehab 1Charlie Sheen isn’t the only one with major issues. Estranged wife Brooke Mueller suffered an apparent breakdown over the weekend as a result of an apparent week-long drug binge and is back in rehab.

The binge capped a week of bizarre behavior that ended with Mueller in rehab for the second time since 2010, according to gossip site TMZ.

The 33-year-old was videoed trying to pawn a pricey watch and stereo equipment to raise some quick cash, even though she reportedly gets $55,000 a month in support payments from Sheen.

The move suggests she may have been trying to conceal the source of the cash so drug purchases would not be traceable.

Friends were tipped that Mueller was using drugs after some reported receiving calls requesting “clean urine,” that is, uncontaminated by illegal substances.

Her efforts apparently were unsuccessful. Mueller reportedly refused a drug test that is required under the terms of her custody settlement with Sheen, according to TMZ.

The return to rehab was described as a precautionary to prevent Sheen from using Mueller’s alleged drug use to regain custody of their twin boys, Max and Bob.

The kids were removed from Sheen’s household in a widely publicized police raid after the boys and Sheen were photographed with his two “goddesses.”
