Actor-filmmaker Brad Pitt secretly joined his former wife Angelina Jolie during a trip to Cambodia in February.
Jolie was in Cambodia for her film "First They Killed My Father".
A source told eonline.com that Pitt was in Cambodia "most of the time except when it conflicted with his own shoot schedule".
A second source said that the former couple's six children, Shiloh, Maddox, Knox, Vivienne, Zahara and Pax, split time between Pitt and Jolie while they go to see Cambodia's sights.
"All through production and filming, and on her most recent press trip, Brad came to Cambodia in secret to spend time with the kids," the second source said.
"They were with Angelina for probably 75 per cent of the time when Brad was in the country and they'd go back and forth between her and Brad."
The insider also said "some or all" of the children would leave Cambodia to fly to Los Angeles to spend time with their father.
"He wasn't in Cambodia the entire time they filmed, but he made multiple trips there to spend time with the kids," the source added.
After a rocky six months since announcing their split, "Brad has been able to spend more time with the kids. He's doing well and is focused on healthy, clean living. He's in a good place".
