A royal flush! Prince Harry and Zara Tindall can't contain their excitement as they watch their horses gallop to victory at Royal Ascot

Horse-loving cousins Prince Harry (left) and Zara Tindall (right) were spotted cheering, whooping and fist pumping as they watched the riders they'd backed win on day one of Royal Ascot. 


Equestrian Zara, 35, looked thrilled to see Harry, 31, and the pair greeted each other with an affectionate hug and kiss (inset). 


While Harry watched the action from the royal box with Prince Andrew, Zara and her friend Dolly Maude clutched each other as the excitement all became too much.
