The troubled Two and a Half Men actor - whose public attack on show creator Chuck Lorre has led to production on the hit series being halted - has revealed plans to visit the Caribbean country, which was devastated by an earthquake in January 2010, to help Sean who has been undertaking charity work in Haiti since the disaster.
Charlie told Access Hollywood Live: "We're going to do a couple things first and then it looks like we're heading down (to Haiti). And I'm excited because, you know, if I can bring the attention of the world down there, then clearly this tsunami keeps cresting."
In a recent interview with US GQ magazine, Sean defended his friend, revealing he believes Charlie simply wants the world to "lighten" up.
He said: "When you divorce the moral judgements, which I prefer to do, I see a guy who has a clearer view of the nature of the world around him than is sometimes comfortable to have. Those are the sort of people who have a tendency to find altered states. But he's a very ironic character. He's got pretension in the crosshairs of his wit. I think to a large degree he's saying, 'Guys, we're only going to be here once, so lighten up.'"
