Brooke Mueller will allegedly file for divorce from Charlie Sheen once his court case is over.

The estate agent - who has 11-month-old twin sons, Max and Bob, with the 'Two and a Half Men' actor - wants to end their two-year marriage as soon as he has stood trial on charges of domestic abuse.

But each one is worried about ways the other one can hurt them
However, Brooke - who is currently receiving treatment for reported drink and drug problems - is said to be worried about what revelations may come out about their marriage if she does leave Charlie.

A source told website Radar Online: "Brooke wants out. She's said it before and she's saying it again right now. She's worried though, because Charlie has a lot of dirt on her.

"The marriage is a nightmare. But each one is worried about ways the other one can hurt them. For Charlie, he's terrified Brooke can help Colorado prosecutors send him to jail. For Brooke, she knows Charlie knows all the dirt about her drug and alcohol use."

Charlie - who is currently in rehab as a "precautionary measure" - will appear in court next month over allegations he attacked Brooke on Christmas Day (25.12.09) during a row at their holiday home in Aspen, Colorado.

It has been reported both Charlie and Brooke had wanted to work on their marriage for the sake of their boys.
