Newest Crazy Hollywood Duo: Charlie Sheen + Sean Penn

As Charlie Sheen continues to make headlines for his outrageous interviews and off-camera antics, the unstable actor has announced plans to team up with actor Sean Penn on a trip to Haiti.

Penn, an outspoken liberal activist who boasts friendships with "21st Century Socialist" Hugo Chavez and communist revolutionary leader Fidel Castro, has made a number of trips to Haiti since the small island nation was struck by a devastating earthquake last year.  He co-founded the J/P Haiti Relief Organization which operates in Port au Prince managing tent cities for displaced refugees and providing emergency medicine, education and community regeneration.

As the Hollywood Reporter notes, Sheen now plans to bring his intense limelight to Haiti, to "bring the attention of the world down there."

Sheen told Access Hollywood that the two plan to visit the country still dealing with the aftershocks of a January 2010 earthquake.

“We’re going to do a couple things first and then it looks like we’re heading down (to Haiti),” Sheen said. “And I’m excited as hell because, you know, if I can bring the attention of the world down there, then clearly this tsunami keeps cresting.”

Penn was one of the friends Sheen mentioned had reached out to him recently, along with Colin Farrell and Mel Gibson.

"They didn't give me any advice. Within that there's great advice," Sheen told ABC News.  "There's just love.  Just seeing what's up."
