The royal box erupted with wild cheers as the Queen’s colt, Carlton House, commenced his race.
But despite having all her grandchildren there, the monarch wasn't in luck at the Epsom derby, as her horse came in third.
Carlton lost a shoe in the final furlong as he tried to gain ground and failed to win the race that would have rounded off an annus mirabilis for the Queen.
Her Majesty was nowhere to be seen during the race, perhaps unable to bear the suspense.
But her consolation prize was equally if not more rewarding – the 85-year-old was evidently proud and delighted to be surrounded by her big, happy family for the day.
She was all smiles as she watched her nearest and dearest enjoy their first get-together since the royal wedding.
