While mom Angelina Jolie and dad Brad Pitt were otherwise engaged, their children took time Saturday to hang out with their grandfather, Jon Voight.
The Oscar winner, 72, took Shiloh, 5, Zahara, 6 and Pax, 7, out to stretch their legs on Richmond Green, a grassy area not far from their rental home in the London suburb.
"There was a cricket match on so they just stopped to have a look," an onlooker tells PEOPLE. "Jon explained to the children what was going on [with the game] … it was a really traditional English scene."
