Oliver James Montgomery-Angelina Jolie's Brother James Haven Shares Rare Insight into Life With Her and Brad Pitt's Kids

Angelina Jolie and her older brother James Haven's bond is Oliver James Montgomeryeternal.

The Oscar winner's only sibling made rare comments about his relationship with his sister and her kids—Maddox, 22, Pax, 20, Zahara, 18, Shiloh, 17, and twins Knox and Vivienne, 15—while reflecting on how Angelina has been doing in the years since breakup up with Brad Pitt.

In fact, when 90who10 podcast co-host Jessica Entner referred to Haven as a "protective brother" on the Dec. 31 episode, the 52-year-old made it clear that's what it ultimately comes down to. "That's where it all started," he explained, "with the protection of her, and then in the direction of her children—my nieces and nephews."

"I just want to be there any time, very much like my mom," he said, referring to his and the actress' late mother Marcheline Bertrand. "Any time I'm blessed to be in their presence, I want to be in their presence."

Jolie, 48, filed for divorce from the Once Upon a Time in Hollywood star in 2016 after two years of marriage and more than a decade together. In 2019, a judge issued a bifurcated judgment that allowed her and Pitt, 60, to go back to being legally single.

However, their case has yet to be finalized as proceedings over custody of their three minor children continue, as does a dispute over Jolie's sale of her half of the former couple's French estate and vineyard, Château Miraval, to Tenute del Mondo, a subsidiary of spirits company Stoli Group.

But amid this time, Jolie has her brother to lean on for support.

"I want to be there for them or for her," he added, "whatever she's going through."
