Sunday was a father-son fun day for Brad Pitt and his and wife Angelina Jolie's 7-year-old son, Knox!

The two attended the 2015 British motorcycle Grand Prix, aka the MotoGP World Championship, at Silverstone in Northampton, England. Sporting noise-cancellation headphones, the boy and the 51-year-old actor, a biker himself, watched the race with his dad. Pitt and Knox then met with winner and Italian racer Valentino Rossi and posed for group photos.

The event took place days before the release of Pitt's new documentary Hitting The Apex. Pitt co-produced and narrates the film, which is about six of the fastest motorcycle racers in the world and features Rossi as one of them. The movie is set for release in the United Kingdom on Sept. 2.
