Their visit was so low-key, one amazed resident shouted, "Are you Brad Pitt?"
According to the newspaper Panama America, the actor replied with a smile: "Sometimes."
The day before, the couple dropped in on a former U.S. military base and the construction site of Panama's new Biodiversity Museum, which will trace the country's natural history and include a botanical garden, the Associated Press reports.
The museum's designer is Pitt's pal, Los Angeles-based architect Frank Gehry, with whom the actor collaborated on designing a seaside development in Britain, PEOPLE reported in August 2005.
The AP reports that the couple planned to ring in the New Year in Costa Rica, where they'd spent Christmas with refugees from Colombia.
