Knox Jolie-Pitt is proving that sports remain one of his biggest passions. The 17-year-old son of Angelina Jolie and Brad Pitt was recently photographed during an outdoor training session in Los Angeles, California, where he appeared focused and determined while running alongside a group of athletes.
For the workout, Knox opted for a casual athletic look, pairing running shoes and sports shorts with a black T-shirt featuring legendary boxer Muhammad Ali.
The choice of clothing offered a subtle nod to one of the most celebrated figures in combat sports history and reflected the teenager’s growing interest in athletic disciplines.
In the photos, Knox can be seen sprinting through the streets of Los Angeles, maintaining an intense pace as he trained under the California sun. His bright orange hair added a bold touch to his sporty ensemble, while his concentrated expression suggested he was fully committed to the session.
