Charlie Sheen has allegedly called estranged wife Denise Richards a "fat, jobless pig" in leaked emails describing their bitter divorce and custody battle.

According to reports emails and court documents were leaked to FoxNews.com, who revealed the pair's splintered relationship.

One paper reveals Richards attempt to limit Sheen's access to their daughters Samantha, 3, and Lola, 2- challenging the joint custody agreement already in place.

She also claims Sheen has refused to allow the two girls to be vaccinated, because he believes they will be harmed. 

Samantha's doctor backs up Richards' claims, revealing she resigned because of "differing philosophies pertaining to Sam's preventative care, I cannot, in good conscious (sic) continue to treat her."

Richards goes on to claim Sheen is a bad father and still uses prostitutes, takes drugs and gambles.

FoxNews has also obtained emails Sheen sent to Richards in the last two months, including one on 22 August (07), in which Sheen allegedly wrote, "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 f**k yourself, sad, jobless pig."

In another he allegedly insulted the actress' cancer-suffering mother: "Go cry to your bald mom, you f**king loser."
