The Duke and Duchess of Cambridge have a close bond with Mike and Zara Tindall, and their kids are of similar ages, and the two families shared a day out together last week.
Meeting at the Burnham horse trials in Norfolk, close to Prince William and Kate Middleton's country home Anmer Hall, where they have been staying during the Easter holidays.
Photos showed Kate giving Charlotte a shoulder-ride, and Prince William doing the same for his goddaughter Mia Tindall. Meanwhile Mike Tindall balanced Prince George on his shoulders.
Zara Tindall was taking part in the races, so the families were out supporting her. Prince Louis was not present at the event, thought to have stayed home with the family's nanny.
Prince George has not been seen in public since last year, and looks very grown up pictured with Mike.
The Tindall's baby daughter Lena, Prince Harry's goddaughter, was also present, all snuggled up in a stroller on the sidelines.
The Duchess of Cambridge kept watch over her two eldest children, Prince George and Princess Charlotte on the day out.
