Celebrity pals Woody Harrelson and Owen Wilson have been giving Peruvian fans a thrill - by bathing in their underwear. The two actors, who are on retreat in the Peruvian jungle, were spotted swimming in an irrigation, wearing nothing but their boxer shorts. The couple is staying off the beaten track on the trip to the Andes area of Peru, where they have visited an orphanage. Wilson is still recovering after attempting suicide at his Santa Monica, California home this summer (07).
