We didn’t think the Denise Richards and Charlie Sheen custody battle could get any worse, but it has. Court papers against ex-husband Sheen have been made public, and it’s not pretty.

Fox News managed to obtain a copy of the papers, and in them Richards listed that the conflicting views her and Charlie had to medically treat their daughters is one of the reasons she wants custody. Apparently Sheen refused to let the girls have common vaccinations because he thinks they will be harmed.

As a result, a letter from the pediatrician, Jeannette J. Levenstein, states that she resigned as the child’s doctor because of “differing philosophies pertaining to Sam’s preventative care, I cannot, in good conscious [sic] continue to treat her.”

She also claims that Charlie still has drug and gambling troubles, and he is also still getting his kicks from prostitutes.

That’s not all though. Charlie sent some malicious emails to Denise which not only taunted her, but took digs at her mother who is undergoing breast cancer treatment.

They read: “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 fuck yourself, sad, jobless pig.”

And: “Go cry to your bald mom, you fucking loser.”
