It's been four years since Pax was plucked out of an orphanage in Vietnam's Ho Chi Minh City, and the seven-year-old was overcome with emotion when he went back to his homeland for the first time this week, Breaking Celebrity News has learned.

Brad Pitt and Angelina Jolie's adopted son was a miserable sight as he was persuaded to get on the plane to depart from Con Dao airport, and Breaking Celebrity News has photos of his sad farewell.

Oscar-winner Angie had to put on her best performance on Wednesday to persuade Pax to join his five brothers and sisters on the flight home, while the child dragged his heels and looked like he was going to burst into tears.

The family had made a special diversion to Vietnam after attending Brad's Moneyball premiere in Tokyo because they thought Pax should see where he was born, Jolie revealed.
