It's rare that we catch a glimpse of one of the Jolie-Pitt kids on their own, but Knox, Angelina Jolie and Brad Pitt's youngest son, 7, got a chance to hang out with his dad solo on Sunday, Aug. 30!
The duo attended the 2015 British motorcycle Grand Prix in Northampton, England. Knox, who wore noise-canceling headphones during the race, met and posed for pictures with winner Valentino Rossi.
The father-son bonding comes just a few days before the release of the 51-year-old's new documentary, Hitting the Apex, which he co-produced and narrates. The film chronicles six of the fastest motorcycle racers in the world.
Knox's siblings, Maddox, Pax, Zahara, Shiloh and twin Vivienne stayed at home for the event. Scroll through the gallery above to see how much each of them has grown!
