And the back and forth drama between Charlie Sheen and his ex-wife Brooke Mueller rages on.

Sheen and his pack of legal hyenas just declared legal war on Mueller and will not only ask a judge for full custody of their twins, he wants to cut off the child support he’s paying her.

Sheen’s lawyer, Mark Gross, just gave Brooke’s  attorneys notice that he’s going to court tomorrow in an attempt to change the custody arrangement. Gross will ask the judge to strip Brooke of both legal and physical custody, on grounds she has relapsed and went back into rehab.

Unfortunately for Brooke, if the judge does award Charlie full custody, Gross wants the judge to terminate Charlie’s obligation to pay Brooke $55,000 a month in child support, since she would no longer be incurring those expenses.

Not to be outdone, Brooke’s lawyers are planning their own offensive, asking the judge for full custody. And, Brooke’s lawyers want Charlie to be psychologically evaluated.

Talk about baby mama drama.
