The former Two and a Half Men star posted the comments online before later deleting them, tmz reports.
He says that a friend told him about a six-year-old girl who was refused an autograph by Kardashian.
“She cries about it every night before she goes to sleep,” he told the reality TV star. “You are lucky that ANYONE cares about your gross and giggly [sic] bag of funk you dare call an ass.”
“Your public loves u. give something back or go f yourself,” he continued.
Sheen however seems to show some respect for Kardashian’s husband, Kanye West, as he has a final parting shot at his wife.
“My apologies to your hubby, great guy I’m sure, I hope his vision returns one day,” he says.
No word back yet from the Kasdashian camp.
