Actress Denise Richards has denied claims made by her ex-husband Charlie Sheen that she wants him to provide a sperm donation so she can have another child. The couple, who have two daughters, finalized their divorce last November, although Sheen is heading back to court to try and prevent Richards from phoning him whenever she likes, and to revisit custody terms.

However, Sheen now alleges Richards asked for a sperm donation.

He says, "There was a request for a donation. Without getting into it here, there is a specific document relating to this that I am going to reserve for a court."

But Sheen, who is currently engaged to actress Brooke Mueller, has no intention of providing a donation: "I would sooner, in actually what I'm wearing, walk on the surface of the moon."

Richards has denied Sheen's claims.

She tells website PageSix.com, "I don't want another child right now. I have my hands full."

However, Sheen blasts back, "She can make every claim in the world. But what she stated in something she wrote would completely and totally defy that."
