Hollywood [Fox News]- Forget Britney and Kevin. The Denise Richards-Charlie Sheen divorce and custody battle is the worst ever in Hollywood. Even Alec Baldwin and Kim Basinger look better by comparison.

In the latest round: I’ve seen papers filed on Sept. 18 by Denise that are absolutely mind-blowing. They confirm the worst things we’ve ever heard about “Two and a Half Men” star Sheen, enough to explain that he may be the “half” in the title of that show.

First, Richards has filed a show cause order to limit Sheen’s visitation with Samantha, 3, and Lola, 2, to days only and no more overnights at his house. Richards also asks the court to initiate a custody evaluation and to give her final decision power despite their joint custody arrangement.

One reason for this may be Sheen’s chronicled paranoia regarding medical needs for the girls. In Denise’s accompanying declaration she describes how Sheen refuses to let the girls have common vaccinations because he thinks they will be harmed.

An attached letter from little Samantha’s former pediatrician supports this. The doctor, Jeannette J. Levenstein, actually resigned as the child’s physician in 2004 because of “differing philosophies pertaining to Sam’s preventative care, I cannot, in good conscious [sic] continue to treat her.”

Believe me, Hollywood doctors never turn away celebrity patients unless they think something is very, very wrong.

Denise’s long declaration filed with the court describes Charlie as abusive, a patron of prostitutes and negligent when it comes to their little girls. It also outlines his sizeable gambling and alleged drug addictions.

Some of this comes as news; in Hollywood, though, a lot of it is well-known and even has been published in tawdry books. There almost isn’t a prostitute in town who hasn’t either named Sheen as a client or outlined his peccadilloes. The fact that Richards married him knowing all that certainly underscores her own lack of character judgment.

But in addition to the declaration I’ve also run across e-mails sent by Sheen to Richards just a couple of months ago that outline the nature of the ongoing battle. For example, on Aug. 22 Sheen wrote to the mother of his children: “You are a pig. A sad, jobless pig who is sad and talentless and, um, oh yeah, sad and jobless and evil and a bad mom, so go [expletive] yourself, sad, jobless pig.”

That’s not all. In other e-mails, Sheen ridicules Richards’ mother, who is undergoing treatment for breast cancer. “Go cry to your bald mom, you [expletive] loser,” Sheen writes.

The actor also regularly chastises Diana Alvarez, the nanny who accompanies the children to his house. “Any hired help who tells me, in my house, that she has a more protective and stronger sense of what’s best for the girls is going to be told to shut their mouth and just do their job.”

Alvarez, still the kids’ nanny but not at Sheen’s, has given her own declaration to the court in support of Richards. She outlines the final time she took the girls to Sheen’s house.

She and Sheen and his fiancée sat down, Alvarez recalls, to discuss Sheen’s hair-trigger temper, his preference for the older girl vs. the baby and his distrust of the nanny as a “spy” for Richards.

Sadly, the talk didn’t work. Sheen, Alvarez says, berated her loudly and abusively with a barrage of four-letter words. The nanny called her husband for assistance and Richards to come take the children. Later, after Alvarez was home, she swears in her declaration that she received this text message from Sheen:

“The girls won’t remember you or even care about you. You couldn’t have done worse if you tried. Thank God they’ll no longer be exposed to someone SO WEAK. Go have a kid of your own. Maybe that way you’ll stop … confusing the fake kids for a real one. Oh, but that might take some guts. Something you so obviously lack with hopeless vacuity.”

Looking through this latest show cause order, almost 240 pages of documents, e-mails and letters, one thing plagues me in this scandal. Sheen’s parents, Martin and Janet Sheen, are two of the nicest people you could ever hope to meet.

Married for decades, they’ve certainly endured problems common to Hollywood couples. But they’re still together and seem very much in love. What could possibly be the explanation for Charlie Sheen’s bizarre personal life?

He’s a talented actor and Oscar and Emmy nominee who’s taken the term “dark underside” to new and frightening levels.

More tomorrow, undoubtedly…
