Brad Pitt spends quality time with son Knox at racing event in the UK

His motoring documentary, Hitting The Apex, will be released in cinemas in a matter of days.

And Brad Pitt reiterated his love of racing as he attended the MotoGP British Grand Prix race at Silverstone in Northamptonshire, England, on Sunday, where he was joined by his young son, Knox. 

The 51-year-old star looked every inch the doting father as he and his seven-year-old look-a-like watched the event and even shook hands with some of the drivers. 

Shielding themselves from the dreary British weather, Brad and Knox watched the race from beneath a rain cover, with the youngster protecting his ears from the sound of the motorbikes with a pair of green ear defenders.

Brad sat his son on his lap as they caught the race on some small screens whilst the rain downpoured. 

Once the weather had brightened up, the Fury actor and his little one made their way outside of the shelter and watched from behind the fence.
