Angelina Jolie and Brad Pitts son is reunited with biological grandmother

The Brangelina clan has just arrived home from a family trip to Vietnam, where eight-year-old son, Pax, met with his biological grandmother, Nhan Dung.

An insider told US Weekly: It was a one day visit. Nhan was looking forward to it after Pax had lived so many years abroad.

Pax, was just three when Angelina Jolieand Brad Pittadopted him from an orphanage in Ho Chi Min City, in Vietnam in 2007, and this is the first time he has been back to his birthplace and met part of his biological family.

The Tomb Raider star - who also raises, Cambodian-born Maddox, 10, and Ethiopian orphan Zahara, six, as well as biological kids Shiloh, five, and three-year-old twins Knox and Vivienne has recently revealed she is keen to keep the kids close to their roots and heritage and educate all her kids on their siblings backgrounds.

Angelina recently explained: "We have teachers who teach Cambodian and Vietnamese in our house and they know their flags, their music and quite a lot about their culture. We bring in as much as we can."

Its reported that Angelina encouraged Pax to say thank you in Vietnamese while they were on their trip.

Angelina and the kids arrived back in the US this morning, while Brad left them two days ago to promote his new film Monsterball in South Korea.

It seems theres nothing this family cant do be Hollywood mega-stars, run a film production company, raise six children, look (very) beautiful AND still find the time to take the kids back to their roots. Big parenting points to Brangelina!
