Dear....

Dear Charlie Sheen,

Please Charlie, don't look at this kind of stuff in front of the kids. Here's the story:

Richards' Shocking Allegations Against Sheen:

TMZ has learned that Denise Richards' lawyer went to court Friday, alleging that her estranged husband Charlie Sheen has threatened her and that his alleged pornography and prostitution habits have put their children at risk.

In the documents, filed Friday in Los Angeles Superior Court, Richards alleges that Sheen pushed her, shoved her and threatened to kill her. Richards also claims in her declaration that Sheen made threats against her parents.

Richards says that during their reconciliation last September, she discovered Sheen was visiting websites with "very young girls, who looked underage to me, with pigtails, braces, no pubic hair, performing oral sex with each other."

Oh BTW Charlie, what's the name of those sites that you're looking at. I....ahhhh a friend of mine wants to know.
