Growing up as a "Brangelina" kid was never going to be normal. Honestly, how could it be? When Knox and Vivienne Jolie-Pitt were born in Nice back in 2008, the first photos of them reportedly sold for $14 million. Fast forward to 2026, and the twins are officially hitting that massive milestone: they’re turning 18 this July.
It’s a huge deal. For years, Angelina Jolie has been vocal about her desire to leave Los Angeles, often mentioning that she’s been tied to the city primarily because of custody arrangements. With the youngest twins reaching adulthood, that legal tether to Southern California is basically dissolving.
Why 2026 is the Turning Point for Knox and Vivienne
The twins have always been the most elusive of the Jolie-Pitt pack. While we’ve seen Maddox, Pax, and Zahara forge very specific public identities—from studying at Yonsei University to launching fashion brands—Knox and Vivienne stayed in the shadows for a long time.
That changed recently.
If you caught the 2024 Governors Awards, you saw a version of Knox that made everyone double-take. He’s tall. Really tall. Standing next to his mom on the red carpet, he sported a buzzcut and a classic tux, looking so much like a young Brad Pitt it was almost jarring. But despite the Hollywood looks, Knox isn't chasing the "nepo baby" acting track.

Knox: The Fighter in the Family
Knox has found his own lane in Muay Thai. It’s not just a hobby; he’s been competing. In July 2025, he actually won his second IKF Point Muay Thai Technical competition. While most celebrity kids are at Coachella, Knox was spotted at a school gym with purple-dyed hair and glasses, focused on combat sports.
He’s private. Like, really private.
Sources close to the family often describe him as a "quiet observer." He’s the guy you’ll see helping Angelina with groceries or running solo trails in LA, usually with headphones in and zero interest in the paparazzi hovering nearby.
Vivienne: The Theater Head
Vivienne is a different story, though she shares that same "behind-the-scenes" DNA. She basically became her mother’s boss during the production of the Broadway musical The Outsiders.
"She’s a very tough assistant," Jolie told People. "She’ll correct me. She’ll say, 'Didn’t you read the memo?'"

Vivienne’s interest in theater isn't about being under the spotlight. She’s focused on the mechanics of storytelling. In the playbill for The Outsiders, she notably went by Vivienne Jolie, dropping the "Pitt" professionally, following the lead of her older sisters Zahara and Shiloh. It’s a subtle but loud statement about where her loyalties lie as she enters her adulthood.
The "Exit Strategy" from Hollywood
The big rumor—which feels more like a confirmed plan at this point—is the family's move abroad. Angelina has already listed her $25 million Cecil B. DeMille estate in Los Feliz.
Why now?
Because the legal "end is in sight."
Once Knox and Vivienne turn 18 in July 2026, the custody battle that has defined their entire adolescence is effectively over. The twins will be legal adults, free to live wherever they want. For Angelina, that means Cambodia or Europe. For Knox and Vivienne, it likely means a life far away from the "toxic" (Angelina's words) environment of Los Angeles.

Where does Brad Pitt fit in?
It's complicated. You've probably heard the reports that Brad has "limited contact" with the twins. While he reportedly had visitation rights during their younger years, the bridge seems to have burned as they’ve aged. While Shiloh legally dropped "Pitt" on her 18th birthday, Knox and Vivienne haven't made a formal legal filing yet—but the professional use of "Vivienne Jolie" suggests the writing is on the wall.
What to Expect Next
As the twins transition into their 18th year, expect a total shift in how they navigate the world.
- Higher Education: Don't be surprised if they skip the US college circuit for international universities, similar to Maddox’s stint in South Korea.
- Creative Ventures: Vivienne is already a credited producer's assistant; look for her name in indie theater or film credits (likely without the Pitt surname).
- Athletic Pursuits: Knox seems genuinely invested in the martial arts world. He’s not training for a movie role; he’s training for the sport.
The narrative of "the twins" is finally splitting into two distinct paths. Knox is the athletic, low-profile observer; Vivienne is the sharp, theater-focused creative. They are no longer just the "babies" of the family—they are the final chapter of a very long, very public Hollywood transition.
Your Next Steps for Following the Story:
Keep an eye on international film festival credits and New York theater rosters. If you’re looking for Knox, check the IKF (International Kickboxing Federation) regional results rather than the IMDB "New Cast" lists. The move abroad is expected to happen by late 2026, so look for the final sale of the Los Feliz property as the definitive signal that the LA era is over.
