Charlie Sheen has admitted he has not married girlfriend Brett Rossi and says he just wanted to wind up his ex-wife Denise Richards with his wedding tweet.

The 48-year-old Anger Management star tweeted over the weekend that he had married his girlfriend, but has since told gossip site "I wanted to give Denise a stroke!!!”

Sheen and Richards have been embroiled in bitter war of words on the social networking site of late, with the situation reaching boiling point over Christmas.

Sheen tweeted at the time: "lemme see if I got this straight; you won't even spring the girls for 30 mins, from the 10 mil house I gave you, (100 yds away) to come down and open the gifts their dad bought them before they leave??’”

Richards responded on Christmas Eve with: "“@charliesheen U done ranting? keep it classy dude. Our kids don't need to be privy to this, U are welcome 2 spend xmas w/us Hope u still come.”
