Charlie Sheen threatens to put Ashton Kutcher 'on a hospital food diet'

After calling actor Ashton Kutcher "lame" and "sidekick" in the past, actor Charlie Sheen attacked the former on Twitter again by threatening to put him on a hospital food diet.

Sheen was replaced by Kutcher on the Two and a Half Men TV show in 2011.

Kutcher blasted him during an interview on the show Jimmy Kimmel Live, Wednesday night, saying: "Dude, shut the f**k up! Enough already. It's three years later and you're still blowing me up on Twitter. Come on dude, really?"

Sheen took to Twitter on Thursday morning to apologise for his bitter attitude, but soon tweeted threats, reports mirror.co.uk.

He tweeted: "Ashton, message received. So sorry, you sounded like me! Well done! My bad I was pissed at other crap and took it out on you. Hope you are good."

Minutes later, he added: "But news flash Dood, you ever tell me to shut the f*** up, ever again, and I'll put you on a hospital food diet for a year...."
