The post in question – made on Father’s Day – saw Pax hold nothing back as he aired his obvious frustrations and let his feelings towards his adoptive father known.

Pax was adopted by Angelina Jolie from an orphanage in Ho Chi Minh City, Vietnam, in 2007. Pax was just three years old at the time, having been left in the orphanage as a newborn baby by his biological mother, who was addicted to heroin.

As per reports, Pitt became Pax’s adoptive father almost right away, but it would appear that not all has been smooth sailing with regards to their relationship.

You have made the lives of those closest to me a constant hell,” Pax allegedly wrote on his private Instagram account in 2020.

“You may tell yourself and the world whatever you want, but the truth will come to light someday.

He finished: “So Happy Father’s Day, you f*****g awful human being.”

According to new reports citing an insider, Troy star Brad is finding it “depressing to see this dragged up” again years after the fact.

A source close to the matter told The Sun: “It’s frustrating to see Brad being painted as some kind of ”bad person’; when it’s far from the truth.”

It was also claimed that Brad has “great respect” for all of his children, and is maintaining a “dignified silence” where Pax’s unearthed post is concerned.
