Charlie Sheen Slams Ex-Wife Denise Richards... Plus her Epic response

Two can play at that game: Denise Richards has responded to her ex-husband Charlie Sheen's erratic rant, in which he branded her a 'washed-up piglet shame pile'

'Brooke M is a sexy rok star whom I adore,' Charlie posted on Sunday. 'D Richards is a heretic washed up piglet Shame pile.'

'Happy Father's Day!!!' he added.

The context of this incredibly bizarre message was not immediately apparent, although Charlie's relationship with the mothers of his four young children has been volatile for years.

A second message posted an hour later by Charlie indicated that he and Denise might be fighting about access to their two daughters, 11-year-old Sam and 10-year-old Lola.

'Father's Rights! I INSIST we devour the mendacity of these "kidnapping" D Richards "types" & bring justice to "us,"' Charlie tweeted without context.

Two hours after the initial tweet, Charlie made it clear in a follow-up rant - one too long for Twitter - that his beef with Denise was related to some conflict over money.
