Charlie Sheen's ex-wife is only after his money, he claims. According to the "Anger Management" star, Brooke Mueller is only going after the custody of their young sons because she wants to continue receiving the $55,000 a month child custody that comes with them.

Charlie's legal team is trying to prevent Brooke from taking the temporary custody of 4-year-old twins Bob and Max from actress Denise Richards, another ex-wife of Charlie.

Denise currently has the twins' custody while Brooke stays at The Betty Ford Centre, where she is seeking help for her substance abuse. Brooke wants the custody temporarily transferred to her brother until she gets out of the rehab.

But Charlie wants to prevent her from taking his sons away from Denise, with whom he has two daughters, Sam and Lola. He believes that Denise is the best person who can take good care of his sons.

Also, he thinks that Brooke only wants his brother to get the custody of her boys because she doesn't want to lose Charlie's $55,000 monthly support payment.

Denise allegedly also has written proof supporting Charlie's claim. According to TMZ, she has text messages from Brooke in which the latter made it clear that she only wants the money and not her children.

Charlie wants Denise to keep the twins until Brooke can prove that she's sober. He is prepared to pay Denise child support for his sons in addition to the monthly check she receives for their daughters. He is also aware that Denise could have custody for a year or longer.

Charlie and Denise were married in 2002, and divorced in 2006. They have had a difficult post-divorce relationship, with each threatening to have the custody of their daughters stripped away from the other. Fortunately, the two have put their differences aside, and are now good friends.

Denise recently even posted a photo of her on Instagram, thanking her "greatest ex" for allowing her to fly in his private plane on Mother's Day so she can take their kids to school.

Brooke, on the other hand, has a tumultuous relationship with Charlie even before they divorced in 2010. They were married in 2008.
