(Cover) - EN Showbiz - Brad Pitt and Angelina Jolie have taken their son Pax back to his homeland of Vietnam.

The Hollywood stars adopted the seven-year-old boy from the country four years ago. They also have Maddox, ten, from Cambodia and six-year-old Ethiopian Zahara, as well as biological children Shiloh, five, and three-year-old twins Knox and Vivienne.

Brad and Angelina have regularly spoken of wanting to ensure their adopted kids grow up knowing about their place of birth.

They have put that into action this week, by taking a trip to Ho Chi Minh City. They gave Pax a home after discovering him in an orphanage there when he was three.

Pax was seen exploring the city with Angelina yesterday.

The Hollywood icon seemed happy and relaxed, wearing a flowing blue dress as she showed her son around. Brad was seen in a simple white suit.

Earlier in the day, Brad and Angelina enjoyed a meal together at a local restaurant. It's thought the pair might pay a visit to Pax's old orphanage while in the city.

The pair were previously in Japan at the premiere of Brad's movie Moneyball. (C) Cover Media
