Sean 'Poncho' Penn Dons Traditional Bolivian Outfit And Hat (PICTURES)

US actor Sean Penn has been pictured wearing traditional Bolivian traditional dress during his tour of South America, where he has been speaking out against British "colonialism" of the Falkland Islands.

The Hollywood star wore the garb and a miner's hat during a meeting with Bolivia's president Evo Morales at the presidential palace in La Paz.

Earlier this week Penn made headlines when he attacked Britain's decision to deploy Prince William to the region as a search and rescue pilot.

"The world today cannot tolerate ridiculous demonstrations of colonialism. The way of dialogue is the only way to achieve a better solution for both nations," he said on Monday.

He was branded an "idiot" and a "fool" by Simon Weston, a British veteran of the Falklands war for wading into the dispute.

Penn made the comments as he toured South America in his role as Haitian ambassador-at-large.
