Brooke Mueller has been at the same rehab facility as Lindsay Lohan while her ex-husband’s other ex-wife, Denise Richards, has temporary custody of her 4 year old twins, Bob and Max.

But Charlie Sheen is meeting Mueller in court on Wednesday because he’s accusing her of using their children for money.

According to TMZ, Mueller is trying to get the courts to approve her brother getting temporary custody of the boys instead of Richards until she gets clean. Sheen, however, thinks that all Mueller is interested in is the $55,000/month child support check she gets from her ex, which she would still get if her brother had custody.

Sheen wants Richards to keep the boys until Mueller can prove she is sober and can stay that way.

Furthermore, sources say Richards already submitted proof in the form of text messages that Mueller is reliant on that money she gets from Sheen. In return, Mueller is countering that Richards also only wants the money. However, she has refused extra child support for taking the boys in.

Entertainmentwise notes Sheen is preparing to tell the court he will provide money to Richards to ensure she keeps the kids.

Richards got custody of the twins after the Dept. Of Children And Family Services deemed Mueller wasn’t providing them with a safe environment earlier this month.
