Charlie Sheen is planning to sue his ex-wife Denise Richards for defamation and seek full custody of their two daughters after she told a court he molested them, the New York Post's Page Six gossip column reports.

Last Monday, Richards, 37, who is starring in an E! reality series called "Denise Richards: It's Complicated," presented a video in Los Angeles Superior Court of Sam, 4, and Lola, 3, allegedly acting in a disturbed manner.

Richards' lawyer sought changes to a custody arrangement, citing "serious issues involving the children," and brought the video to bolster her case, but a court commissioner did not view it.

Instead, he listened to two experts' views and ordered changes to the agreement that were characterized by Sheen's attorney as "nothing meaningful" — and by Richards' attorney as beneficial for the pair's two young daughters.

Richards' attorney, Neal Hersh, and Sheen's attorney, Fern Wender, refused to say what type of experts testified, or what was on the video that Richards hoped to introduce.

But a source told Page Six that “Denise’s accusations were vile. She was basically trying to say Charlie manipulated the kids and acted inappropriately with them. It’s disgusting and totally untrue. Charlie is furious. Denise has really pushed it too far this time."

Her evidence was dismissed after Sheen, 43, presented a video of the girls acting normally, according to Page Six.

Sheen is said to be so furious, he's "out to prove Denise's lack of veracity and sue her in civil court for defamation. Then he'll sue for child custody," the source told Page Six.

"She came after Charlie because the ratings on her E! reality show have tanked and they were threatening not to renew," the source said.

"She thinks a court battle would be good for ratings so she wants all overnight visits with the girls ceased, and monitored visits with her nanny. She invited the media circus to the hearing and even wanted reporters in the judge's chambers — which wasn't allowed. It's ridiculous."

The "Two and a Half Men" star and Richards have engaged in a series of bitter fights since divorcing in 2006.
