Charlie Sheen is reportedly making some shrewd financial moves.
According to TMZ, Sheen wants to stop paying Mueller the $55,000 a month in child support he currently pays while she is in rehab. A source close to Sheen told TMZ that the actor doesn't think he should have to pay child support while the children are not in Mueller's care.
The twin boys Sheen and Mueller have together are currently living with another of Sheen's ex-wives, Denise Richards. Richards now has five children in her care, as she and Sheen have two daughters together, and she also has an adopted daughter.
