Angelina Jolie‘s son Knox had a busy day celebrating two big milestones.
The youngest child of Jolie, 51, and Brad Pitt was recently photographed attending his high school graduation — cheered on by his mom — in Los Angeles on Friday, June 5.
And during a graduation speech later posted on social media by a fan account, Knox, 17, could be seen sharing that he would be competing in a Muay Thai fight later that evening.

“Tonight, I’m gonna be fighting at Total Sonic Knockout 5 at 12:45 a.m., so catch me,” he told the audience in the clip.
“I’m gonna knock ‘em the f— out!” he added with a smile, eliciting cheers from the crowd.
Total Sonic Knockout is described as a hybrid combat and rave experience, according to the event organizers’ official YouTube page.
Jolie was spotted at the graduation ceremony snapping photos of her son as he spoke onstage.

The teen’s interest in Muay Thai is nothing new.
In July 2025, Knox won the IKF Point Muay Thai Technical competition in Los Angeles, per TMZ.
Jolie and Knox’s twin sister, Vivienne, were seen cheering him on ringside at the event.
Knox and Vivienne are the youngest of six children shared by Jolie and Pitt, 62. The former couple are also parents to Maddox, 24, Pax, 22, Zahara, 21, and Shiloh, 20.

Knox isn’t the only one of his siblings to show an interest in athletics.
In 2024, choreographer Kolanie Marks shared a since-deleted video on Instagram of Shiloh, then 18, dancing.
Marks previously spoke with PEOPLE about Shiloh’s commitment “to a craft that is extremely hard.”
“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,” he said.
