Actor Charlie Sheen used Father's Day on Sunday to take aim at his ex-wife Denise Richards on Twitter.com, blasting the former Bond girl as a "heretic washed up piglet".
The Wall Street star shares two daughters with Richards, but it seems Sheen was left unhappy with the amount of time he got to spend with the girls this weekend (20-21Jun15) and he made his frustrations clear in a series of posts online.
In his first message on Sunday, Sheen praised his third ex-wife, Brooke Mueller, the mother of his six-year-old twin sons Bob and Max, while slamming Richards in the same tweet.
He wrote: "Brooke M is a rock star whom I adore D Richards a heretic washed up piglet shame pile Happy Father's Day (sic)!"
Sheen went on to call for father's rights, adding: "Cadre: on FD (Father's Day); Father's Rights! I insist we devour the mendacity of these 'kidnapping' D Richards 'types' and bring justice to 'us'".
Richards filed for divorce from Sheen in 2005 after three years of marriage and they subsequently became embroiled in a bitter custody battle over daughters Sam and Lola. They later managed to work out their differences, but famously fell out again in 2013 after Sheen accused Richards of pulling the plug on plans for him to join her and their daughters over the holidays.
His rants on Twitter prompted the actress to hit back at Sheen online, urging him to stop feuding publicly with her for the sake of their kids.
Richards has yet to respond to the latest online attack.
