Charlie Sheen seems adamant to begin 2014 like he ended 2013 - by blasting his former wife Denise Richards on Twitter. Public relations between Sheen and Richards have hit an all-time low after a series of emotionally charged tweets surfaced on Twitter. In a tweet posted Tuesday, Sheen writes, “Hey denise I own the farm. Yet you are the only pig in the pen to sling mud bile & sh—e every inch of your evil cloven hoofs trample (sic). c#oink.”

This new series of tweets comes as a shock to most fans. Relations between the former couple appear to have improved in recent years after their bitter divorce and ensuing custody battle. In May of 2013, Richards took temporary custody of Sheen's twin sons after their mother, Brooke Mueller, was admitted into The Betty Ford Clinic for rehab.

The former couple had a dramatic falling out when Richards allegedly canceled plans for Sheen to join her and their daughters over the holidays. In one tweet, sent before Christmas, Sheen posted up a picture of a souvenir from their wedding, chopped into pieces. Richards politely responded to Sheen by asking him to stop for the sake of the children, and by inviting him to spend Christmas with them.
