Owen Wilson In Peru

Celebrity friends Owen Wilson and Woody Harrelson have been spotted bathing in their underwear in Peru.

The two actors, who were on retreat in the Peruvian jungle, spent their time meditating, walking along the Amazon and swimming wearing nothing but their boxer shorts, reports New York Post.

The pair stayed in a teepee at the Hanaq Pacha Retreat Center, in the Sacred Valley of the Incas.

The back-to-basics resort, sponsored by Woody, is a yoga and spiritual retreat that has its own organic gardens that grows vegetables.

The wood and canvas malocas sleep up to four people and feature furnishings created by local artisans and the kids of the nearby Casa de Milagros, a home for abandoned kids that Woody also supports.
