Season ticket holder Fiona Sturgess told reporters, “Kate said that William was playing football with the children last night and one of them said, I think it was George, ‘Are you playing football tomorrow, Pops?’ “
This isn't surprising, considering Harry and William both call their father Prince Charles 'Pops.'
In a 2016 documentary honouring Queen Elizabeth's milestone 90th birthday, Kate opened up about her children’s special relationship with the monarch – and revealed a special nickname for her.
Kate told ITV’s The Queen at Ninety, “George is only 2 and he calls her ‘Gan-Gan,’ ” Kate said. “She always leaves a little gift or something in their room when we go and stay, and that just shows her love for her family.”
