The entire Jolie-Pitt family of eight arrived at Con Dao Island airport in south-east Vietnam on Friday, from Japan, where Brad had premiered his new film Moneyball last Wednesday.

The stop-off is particularly significant to seven year-old Pax who was born in Vietnam where Angelina adopted him from an orphanage in 2007 when he was three years old. It is thought to be Pax's first venture back to his native country since his adoption, with Angelina telling the Financial Times in July, "We owe Vietnam a visit, because Pax is due."

Pax enjoyed some special mum time, with Angelina taking him out to lunch in Ho Chi Minh City on Friday and local newspaper the VN Express is expecting the family to pay Pax's old orphanage a visit.

Jolie also told the Financial Times that she and Brad make sure that their children are educated about their native countries. "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."

"Z wants to get back to Africa, and Shiloh too. So everyone takes their turns in their country."

Over the weekend Angelina Jolie and Brad Pitt took a rare day trip out as a couple without their kids, visiting the historic prison known as the 'tiger cages' on Con Son Island, the largest of the Con Dao Islands.

The prison is infamous for its ill-treatment of prisoners who were kept in small tiger-like cages during the Vietnam civil war between 1955 and 1975, when the South Vietnamese government used it to hold political prisoners. The prison was closed in 1975 with the fall of Saigon.

The Con Dao Islands are now primarily a national park and have a growing eco-tourism business, with endangered species protected within the park including the hawksbill turtle, the green turtle and the dugong, so there's lots for the kids to explore.
