The actors and their brood were spotted Friday eating lunch at a restaurant in Ho Chi Minh City. This is the family's first trip back to the country since 7-year-old Pax Thien Jolie-Pitt was adopted four years ago.
They arrived in Vietnam after a visit to Japan, where Pitt was promoting his movie "Moneyball."
Jolie and Pitt have three biological children and three adopted from Cambodia, Ethiopia and Vietnam.
