Brad Pitt’s parents William and Jane Pitt have not met their six grandkids for four years now. The actor’s child custody battle with former wife Angelina Jolie is yet to be resolved.

The Troy actor’s mom celebrated her 80th birthday recently. Pitt threw a lavish family party to celebrate the occasion at his Californian beach house.  

It seems the Once Upon a Time in Hollywood star’s six kids were not present in the bash. They were absconding from the photos of Jane with other family members posted on social media, Daily Mail reports.

Brad Pitt's parents have not seen their grandchildren ever since the former couple got engaged in a long and bitter custody and divorce battle. Rumor mills say that the elderly couple could be one of the major casualties in their son’s ongoing court battle.

It looks like the grandparents are among all those grandparents in the United States who have lost touch with their grandkids because of disputes between their adult child and the former or ex-spouse of that child.

In other words, the concept of alienated grandparents has become so common that they have grabbed eyeballs from child development experts, various advocacy groups, and family therapists.

Reports have it that Maddox, Pax, Zahara, Shiloh, Vivienne, and Knox were regular visitors at their grandparents’ home in Missouri. It was a time when their famous parents were still together.

A source insisted that the children used to be uncontrollable. There was a big backyard at their grandparents’ home, which was perfect for campfires in the summer and sledding in winter.

However, all those fun visits came to an end when the 45-year-old actress filed for a divorce against her husband in 2016. The Maleficent actress alleged that the 56-year-old actor could not control his temper and had drinking problems.

Sources, however, claim the key reason why the grandparents are not able to meet the kids is that Jane Pitt did not have a cordial relationship with her estranged daughter-in-law.

A source insisted that Jane Pitt is a devout Christian who criticized gay marriage while Angelina Jolie has a liberal attitude and dated women. So, the duo had not been friendly in the first place. However, the insider feels that nobody thought things would be the way they are, Mercury News reports.

 Meanwhile, the custody battle between Angelina Jolie and Brad Pitt does not seem to end anytime soon. While it was reported last month that there were signs of the former couple’s relationship getting better, Jolie’s recent filing to remove the judge and her ex-husband’s counter-claim has sent different signals lately.
