Hollywood actor Charlie Sheen has slammed his second former wife Denise Richards on social media.
While praising his third former wife Brooke Mueller in one of the posts on microblogging website Twitter, the "Anger Management" star called Richards a "washed up piglet Shame pile", reports aceshowbiz.com.
Sheen posted hateful messages against Richards on Sunday.
"Brooke M is a sexy rok star whom I adore D Richards a heretic washed up piglet Shame pile," he wrote before adding, "Happy Father's Day!!!"
In a second message he shared an hour later, Sheen indicated that he and Richards fought over custody of their two daughters, Sam and Lola.
"Father's Rights! I INSIST we devour the mendacity of these 'kidnapping' D Richards 'types' & bring justice to 'us'," the post read.
Sheen then shared a message which he dubbed "open letter to the media" in a follow-up tweet.
"Denise Richards is a shake down piece of s**t doosh phace & worse mom alive! A despicable charlatan who sux ISIs a**," so he wrote.
He even called Richards an "evil terrorist" and considered her his "enemy."
Although the "Two and a Half Men" actor had since deleted the controversial tweets, his "open letter" can still be found online.
Instead of fighting back at Sheen with the similar outrageous messages, Richards decided to send him lovely Father's Day wish on her Twitter account.
"Happy Dad's Day! @CharlieSheen have a great trip in Mexico! Kids were disappointed u weren't here for it - Hey we'll celebrate when u r back!" so she wrote.
