A one-on-one day out with dad is always special. But when you normally share dad with five siblings and an adoring public, it's extra special!
On Sunday, Brad Pitt took his youngest son, 7-year-old Knox, out for a day at the races in England.
The 51-year-old actor and motorcycle enthusiast shared his passion for bikes with Knox at the MotoGP British Grand Prix.
The two watched the action on the track and mingled with some of the racers.
But Pitt and his look-alike son weren't just at the event for fun. It was a working vacation day for the star, who was also on hand to promote a MotoGP documentary about the six fastest racers in the world, "Hitting the Apex."
Pitt narrates the documentary, which opens in the U.K. Sept. 2.
