Charlie Sheen posts Twitter picture of himself with porn star girlfriend Bree Olson

Charlie Sheen has joined Twitter – using his first post to send fans a picture of himself posing with porn star girlfriend Bree Olson.

The troubled actor, 45, tweeted the snap of the adult ‘actress’ and him holding cartons of fruit juice and chocolate milk along with the message ‘Winning! Choose your vice…!’

Charlie managed to clock up a massive 650,000 followers on the site in less than a day, with users no doubt eager to see if he will launch in to any of his famous rants.

His catchphrase ‘winning’ also became a trending topic on the site, with amused followers either adopting or mocking his slogan.

Piers Morgan, who interviewed the Two and a Half Men star for his CNN show on Monday night, claimed to have talked Charlie into joining the world of Twitter.

He wrote: “I told @charliesheen to join Twitter during commercial break last night. He chuckled and said: ‘That could be fun, maybe I will…’”

Charlie describes himself on the site as an “unemployed winner”, referring to the fact that his sitcom, for which he’s paid $2 million per episode, has now been suspended after he launched in to a furious rant at its creator Chuck Lorre.

He described the writer as “a stupid, stupid little man and a p***y punk that I never want to be like.”

The cancellation is the latest in a series of dramas for the Wall Street star, whose downward descent began last November when he was arrested for trashing a New York hotel room.

Then in January he was rushed to hospital with stomach pains following a three-day bender, causing filming of his show to be temporarily put on hold

Charlie is currently living in a ménage a trois with Bree and his other girlfriend, former nanny Natalie Kenny.

He told radio presenter Howard Stern: “We have two beds in the bedroom… They will take a separate bed and then I have to choose.”

When asked by Stern if the women have sex with each other he replied: “Well, you would have to ask them.”
