Prince George and Mia Tindall appeared to share a secret joke as Princess Charlotte enjoyed the dodgems during a family outing in Norfolk on the weekend.
As reported by The Sun, the two five-year-old cousins appeared to compare their heights while laughing as three-year-old Princess Charlotte went for a spin on a fair ride nearby.
Kate, 37, who was wearing tight black jeans and a Barbour quilted jacket, made sure to keep a close eye on her daughter.
The Duke and Duchess of Cambridge and the Tindalls spent the day watching Zara, a former silver medal Olympian, compete in the Burnham Market Horse Trials.
The 37-year-old triumphed and finished in third and fifth in her events after she fell from her horse last year.
Zara is the only daughter to Princess Anne, who is the Queen’s second child.
Prince George, Princess Charlotte and Mia are three of the Queen’s great-grandchildren — making them third cousins.
During the family day out, Mia was picked up by Prince William to get a better view of the trials.
The Duke was dressed down with trainers, a flat cap and green anorak.
Princess Charlotte rode on the shoulders of her mum and George was on the shoulders of his uncle, Mike Tindall.
George carried a toy sword along as the former England rugby star followed Zara across the parkland during the trials.
The trials are a popular family event and include a bouncy castle and circus workshops for children.
An onlooker said: “They were just like any other family, enjoying a day out and having a lovely time. There were no tantrums thrown by the kids and they all seemed very down to earth.
“A few people noticed them, but generally everyone just carried on as normal.”
