Her latest destination: Vietnam, where she was photographed with her son Pax, 7.
"We owe Vietnam a visit, because Pax is due," Jolie, 36, told the Financial Times
in July, adding of her six children with Brad Pitt
: "They are all learning about each other's cultures as well as being proud of their own. They all have their flags over their beds and their individual pride."
According to the photographer, the actress and Pax went out for lunch together in Ho Chi Minh City, and the rest of the Jolie-Pitt brood is along for the trip as well.
Pitt, 47, and Jolie adopted eldest son Maddox, 10, from Cambodia, Zahara, 6, from Ethiopia. Their daughter Shiloh, 5, was born in Namibia, and twins Vivienne and Knox, 3, in France.
