Sheen started his profanity-laced tirade with, "D Richards is a heretic washed up piglet."
And in classic Sheen form, the insults kept flying. He called Richards the "worst mom alive," an "evil terrorist," and added for good measure, "[Expletive] couldn't act."

Much of what Sheen wrote is too graphic to repeat, but it appears he was angry about money, complaining he's paid his ex "30 mil and she calls me a deadbeat dad," adding, "see you in court."
As for Denise, who has two daughters with Sheen, she kept it classy, tweeting back: "@CHARLIESHEEN Have a great trip in Mexico! Kids were disappointed u weren't here for Father's Day."
