They used to be a happy couple but now they have nothing but problems. Charlie Sheen filed papers with the Los Angeles County Superior Court regarding his visitation rights for his children with Denise Richards according to TMZ.

Sheen is now engaged to Brooke Mueller and says that she: "has a strong relationship with my children and she and I provide them with a structured and safe environment." He wants to spend more time with his children and without nanny supervision. He'd like to pick the two kids Saturday morning and return them on Monday every third and fifth weekend of each month.

Also, Charlie wants Denise to stop calling his house for non-emergencies. He states, (Richards) "has repeatedly made unnecessary telephone calls to me and to my home. These calls have resulted in disputes between us."

Not related to those issues, Charlie has recently accused Denise of wanting him to have another baby with her. He said that he has a specific document stating that and he is saving it for court.
