Denise Richards was slammed via social media harder than any celebrity has been slammed in a long time. Her ex-husband, Charlie Sheen, let loose with a rant about his second ex-wife, in a vulgar exhibition on Twitter.

Among the things former Two and A Half Men star called Denise Richards a ‘shake down piece of sh*t,’ ‘a doosh phace,’ and an ‘evil terrorist sack of landfill rash.’

He went on, calling Richards the ‘worst mom alive,’ and he even insulted her talent as an actress.

“bitch couldn’t act hot in a fire or wet in a pool,” he Tweeted. “you should all hear her acting lessons: sounds like dolphins sucking off Coyotes!!! this gangster Sheenius will be Winning! Duh!! really grandma? I’m the ARCHITECT OF THE TERM YOU LEAKY AND MALARIA RIDDLE PUDDLE OF S–T STINK DECAY!! and now I’m out.”

Do you think Charlie Sheen is drinking and/or taking drugs again? Or was he simply really pissed at Denise Richards on Sunday?

This won’t come as a huge surprise to most, but those rants no longer appear on Charlie Sheen’s Twitter account.

What’s your take on Charlie Sheen’s rant at Denise Richards? Do you think he’s a vile, bitter man or is he perhaps mentally ill?
