Los Angeles: Hollywood star Brad Pitt was taking frequent trips to Cambodia, where Angelina Jolie was filming 'First They Killed My Father,' to spend time with their children.
The 53-year-old star was in Cambodia "most of the time except when it conflicted with his own shoot schedule," reported E! online.
"All through production and filming, and on her most recent press trip, Brad came to Cambodia in secret to spend time with the kids. They were with Angelina for probably 75 percent of the time when Brad was in the country and they'd go back and forth between her and Brad," a source says.
"He wasn't in Cambodia the entire time they filmed, but he made multiple trips there to spend time with the kids," the source adds.
Jolie, 41, who shares six children with Pitt, filed for divorce in September 2016 after two years of marriage. She cited irreconcilable differences as the reason for the split.
