It was a proud watch for Mia, the eldest child of Zara and Mike Tindall, who was all out in full support for her mum and grandmother's passion for equestrian sport.
Mia attended the Gloucestershire competition at the Hartpury International Horse Trials, but, unusually, her father, was absent from the event.
The sweet youngster was deeply involved in monitoring the technical aspects of the performances.
She couldn't contain her excitement and pride during the key moments, beaming with joy as she watched Zara achieve strong rounds in both the showjumping and cross-country events.
A source revealed: 'She was thrilled when her mum completed a clear round in the showjumping and she jumped up with joy when her mum cleared cross country course with ease.'
The source even shared an interesting observation about the proud daughter 'checking the times of the other riders and comparing them against her mum's time in the showjumping,' the witness told the Hello!Magazine.
For the context, Zara's grandmother, Queen Elizabeth, had a lifelong passion for horse racing.
Princess Anne, Zara's mother, also took part in the three-day evening at the 1976 Montreal Olympics, becoming the first British royal to compete at the Games, where she rode the Queen's horse Goodwill.
Zara also won gold at the 2005 European Eventing Championships and silver at the 2006 World Equestrian Games.
