APRIL 21--In a searing court attack on Charlie Sheen, actress Denise Richards alleges that her estranged husband is unstable, violent, addicted to gambling and prostitutes, and visits pornographic web sites featuring young men and girls who appear underage.

In a remarkable sworn declaration (a copy of which you'll find here) filed today in Los Angeles Superior Court, Richards also charges that Sheen, 40, assaulted her and threatened her life during a December 30 incident at the actress's Los Angeles home. Richards claims that an enraged Sheen--who was over for a visit with the couple's two children--told her she was "fucking with the wrong guy" and called her a series of vulgar names in front of the children.

The actor, Richards said, then shoved her to the ground and screamed, "I hope you f--king die, bitch."

As Richards, 35, tells it, Sheen was angry because she had told her divorce attorney about discovering details of Sheen's porn-surfing practices. Richards's declaration, filed in support of her request for a restraining order against Sheen, contends that Sheen "belonged" to "disturbing" sites "which promoted very young girls, who looked underage to me with pigtails, braces, and no pubic hair performing oral sex with each other."

Other sites visited by Sheen, Richards alleges, involved "gay pornography also involving very young men who also did not look like adults." Richards claims that she also discovered that Sheen "belonged to several sex search type sites" on which he "looked for women to have sex with." His online profile, Richards adds, included a photo of "his erect penis."

The Richards evisceration also portrays Sheen as a lousy father who urged her to abort their first child. And, when she was about to give birth to their second child via a C-section, Sheen's attention was "diverted to his pager for the results of his betting."

To illustrate Sheen's volcanic temper and abusive language, Richards's court filing includes transcripts of six phone messages he allegedly left her last April, while she was pregnant with the couple's second daughter. In one call, Sheen says, "You're a coward and a liar and a fucking nigger alright so fuck you." In a second message, Sheen appears to make a reference to Richards's female attorney when he complains about "two pregnant cunts...plotting against the rest of us." (19 pages)
