Angelina Jolie supports son Knox, 17, at graduation before Muay Thai match

Angelina Jolie’s youngest son, Knox, celebrated two major milestones in one day. On Friday, June 5, the 17‑year‑old was photographed at his high school graduation in Los Angeles, cheered on by his mother.

During a speech later shared on social media, Knox revealed his evening plans:

“Tonight, I'm gonna be fighting at Total Sonic Knockout 5 at 12:45 a.m., so catch me,” he told the audience.

“I'm gonna knock ‘em the f--- out!” he added with a smile, drawing cheers from the crowd.

The event, described by organizers as a hybrid combat and rave experience, saw Knox swap his cap and gown for boxing gloves just hours after the ceremony. Photos captured him exchanging punches and kicks with an opponent in the ring.

Knox, who turns 18 in July, has been training in Muay Thai for years. In July 2025, he won the IKF Point Muay Thai Technical competition in Los Angeles, as per TMZ. Jolie and Knox’s twin sister, Vivienne, were spotted ringside supporting him at that event.

Knox and Vivienne are the youngest of six children shared by Jolie, 51, and Brad Pitt, 62. Their siblings include Maddox, 24, Pax, 22, Zahara, 21, and Shiloh, 20.

Athletics run in the family. In 2024, choreographer Kolanie Marks posted (and later deleted) a video of Shiloh, then 18, dancing. He told PEOPLE: “My style is a lot harder for a lot of people, and it's something that she's dedicated herself to trying to figure out.”
