Brad Pitt and son Knox bonded at the race track without Angelina Jolie as they attended the MotoGP British Grand Prix at Silverstone, Northamptonshire in England on Sunday

The actor and his wife were rumored to be house-hunting in England, according to multiple reports.

"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," said Daily Mail.

The British publication added, "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."

Prior to the sighting with their son, Us Weekly previously reported that Angelina Jolie and Brad Pitt are looking for a house in London because, "Angie wants to slowly immerse herself in E.U. Politics."

However, the couple is not rushing their house-hunting in London because apparently, Angelina Jolie "doesn't want to lose her directing momentum."

Brad Pitt has left his playboy ways when he shacked up with Angelina Jolie. Now, the actor is all about family.

Talking to Esquire magazine back in 2013, the "By the Sea" actor said that life has never been happier for him now that he finds himself being a father to three sons and three daughters.

"I have very few friends. I have a handful of close friends and I have my family and I haven't known life to be any happier," he said. "I'm making things. I just haven't known life to be any happier."

Brad Pitt and Angelina Jolie have six children: Maddox, Pax, Zahara, Shiloh and twins, Knox and Vivienne.

He said of being a family man, "I always thought that if I wanted to do a family, I wanted to do it big," he said. "I wanted there to be chaos in the house... there's constant chatter in our house, whether it's giggling or screaming or crying or banging."
