Charlie Sheen has more to get off his chest.
The Two and a Half Men star – who went on a rant against his boss and others last week – offers a look inside his world and says he wants to share his side of the story, in a new televised interview set to air this week.
“I have one speed. I have one gear. Go!” he tells ABC’s Andrea Canning in a 20/20 interview airing Tuesday. “I dare you to keep up with me.”
Sheen, 45, tells Canning, who visited the actor and two female companions at his home this weekend, “I am on a drug. It’s called Charlie Sheen.”
