Jolie and Pitt tour Panama City

Brad Pitt and Angelina Jolie paid a visit to Panama City recently, where they spent time shopping for souvenirs and touring the Panama Canal.

The pair also dropped in on a former US 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.

Residents were shocked to see the high-profile couple, with one amazed citizen shouting: "Are you Brad Pitt?"

According to the newspaper Panama America, the actor smiled and replied: "Sometimes."

The couple were touring the museum, which was designed by Los Angeles-based architect Frank Gehry, a close friend of Pitt's.

The Fight Club star, who is an architecture buff, is collaborating with Gehry on a seaside development in Britain.
