The 50-year-old actor has six-year-old twins Bob and Max with Brooke and claims he can no longer afford the astronomical payments that were previously agreed on when he was earning $613,000 per month on 'Two and a Half Men'.

Charlie - who pays the same amount to his other ex-wife Denise Richards for their daughters, Sam, 11 and Lola, 10 - claims he now makes approximately $87,384 monthly and has filed court documents asking to reduce the payments, according to PEOPLE.

The actor - who revealed last year that he is HIV positive - revealed he pays $105,000 bills per month and an additional $25,000 for medical costs.

However, Charlie admitted to selling his rights to 'Two and a Half Men' for $26,750,000. A hearing has been scheduled for April 13.

It was previously revealed that Charlie's payments to his exes were part of what he dubbed 'Operation Harmony', a plan to have his children and ex-wives live nearby.

He said: "I bought houses in my neighborhood for Brooke and the boys, and then for Denise and the girls. I wanted everybody to be in the same neighborhood. And that all went bad."

Charlie is currently being sued by Denise, who claims he evicted her and their daughters, from their home and also sent aggressive text messages to their younger daughter.

However, one of Charlie's lawyers, Martin Singer, slammed Denise for being "greedy".

Mr. Singer said: "I've been representing Charlie for more than 20 years.

"Patty [Glaser, Denise's lawyer] is just the latest in a long string of lawyers who Denise has hired to squeeze as much money as she can out of Charlie. This motion has nothing do with their children. Denise is simply being greedy."
