Put em up! Knox Jolie-Pitt showed just how fast he's growing up when he was photographed hitting the gym in Los Angeles over the weekend.
The teenager looked to have inherited his famous parents, Brad Pitt and Angelina Jolie's height and looked tall and lean as he carried boxing gloves ahead of his workout.
Knox, 16, had his hands already bandaged and was ready to work up a sweat in the rare images.
He sported short, spiky hair and bore a striking resemblance to both his mom and dad. Knox opted for shorts and a Muhammad Ali t-shirt.
Knox and his twin sister, Vivienne, turned 16 on July 12. They made their debut in the spotlight at just three weeks old, when they appeared on the cover of People's August 2008 issue.
While Vivianne has opted to step into the limelight in recent months working as a production assistant on Tony-nominated musical The Outsiders which Angelina produced, Knox prefers a life away from the cameras.
He did however voice the character of Ku Ku in Kung Fu Panda 3, which was released in 2016, and has walked several red carpets over the years.
Knox is one of six children the former couple share. Along with their twins, they are also parents to Maddox, 23, Pax, 20, Zahara, 19 and Shiloh, 18.
Shiloh made headlines recently after it was revealed she had filed to drop Pitt from her name after turning 18.
She wants the courts to allow her to be known as Shiloh Nouvel Jolie as the children's relationship with Brad is reportedly strained. The hearing is set for August 19.
Shiloh is the first of Angelina and Brad's children to make the change official although Vivienne, Zahara, and Maddox also omit the name Pitt from public appearances.
Vivienne was also credited as Vivienne Jolie in the playbill for The Outsiders.
To change your name in California, the person needs to publish legal forms in a newspaper for one month.
The request will then show up in the legal notice section of the publication.
Shiloh posted her announcement in the Los Angeles Times.
Her attorney Peter Levine told Us Weekly: "As Shiloh's attorney, I am required to publish a legal notice because the law in California requires that of anyone who wants to change their name.
"That legal notice was published in the Los Angeles Times, as is required."
Brad and Angelina tied the knot in 2014 after nine years together, but split two years after their nuptials.
They've been embroiled in ongoing divorce drama since and while they were declared legally single in 2019, their divorce has not been finalized.
They continued to battle it out over their winery Chateau Miraval and custody of their minor children too.
