The Jolie-Pitt Twins Turn 18 on July 12, the Same Day Their Parents’ Divorce Is Expected to Finally Close. Knox Is Spending the Countdown Sprinting Through Los Angeles with a Trainer.

Knox Jolie-Pitt turns 18 on July 12, 2026, the same day his parents’ divorce is expected to finalize after nearly 10 years in court. New Backgrid photos caught the teen mid-sprint through Los Angeles streets with a trainer, the latest entry in a fitness routine that’s become its own running storyline.

Combat sports are his main thing. He trains Muay Thai several times a week, stepped into an exhibition fight on June 6, and recently turned up with bright orange hair and tiger-print shorts. Fans in Thailand have noticed, especially when he wears gear referencing the country’s historic stadiums.

His twin sister Vivienne shares the birthday, and the date carries weight beyond cake. Page Six reported that Angelina Jolie plans to leave the U.S. once the twins reach adulthood, closing one chapter as Knox very visibly sprints into the next.
