Brad Pitt was reportedly left heartbroken when he briefly met his son Maddox Jolie-Pitt during the first and only reunion following his the split from Angelina Jolie. According to a latest report, the 15-year-old allegedly used some hurtful words when he met The Allied star on 19 October.

Maddox told the 52-year-old actor: "You're not my father!" Star magazine quoted a source as saying. (Via HollywoodLife)

"It was really tense — and then Maddox suddenly lost his temper... and stormed out of the room!" the source said.

Maddox "couldn't control himself and just exploded," the source added. The 15-year-old was adopted by Jolie in 2002 and then by the Fight Club actor in 2005.

Earlier, a report by Us Weekly had claimed that Maddox had refused to attend the reunion, which was conducted in the presence of DCFS (Department of Children Family Services) personnel.

During the reunion, the 52-year-old actor reportedly broke down in front of his children.

"It was a very emotional meeting," a source previously told InTouch magazine. "Once the kids came in, [Brad Pitt] lit up. He had tears in his eyes and tried to hold it together because he didn't want them to get upset because he was crying. The visit was gut-wrenching: Vivienne, 8, and Zahara, 11, both started crying, asking when they could go home [to Brad's compound in LA's Los Feliz neighbourhood]."

Brad and Jolie split after the Original Sin actress filed for divorce on 19 September, citing "irreconcilable differences". The former couple started dating after meeting on the sets of the movie Mr and Mrs Smith in 2005 and got married in 2014. The duo shares six children: Pax, 12, Zahara, 11, Shiloh, 10, Maddox, 15, and twins, Vivienne and Knox, 8.
