They're the golden couple openly sharing the love at the Olympics.

Prince William and Kate Middleton, the Duchess of Cambridge, have been thrilling Olympic fans with their heart-warming public displays.

The pair, along with William’s brother, Prince Harry, are Olympic ambassadors and they’ve been doing their fair share of sporting diplomacy, visiting athletes in the village and attending the equestrian events, rowing, tennis and cycling.

While watching Andy Murray’s match yesterday they joined the Wimbledon crowd in a Mexican wave before dashing across London, fitting in a change to more casual outfits, to the cycling velodrome.

Accompanied by Harry and Sophie, Countess of Wessex and the British PM David Cameron, the couple beamed as they whooped and hollered while watching the British men’s pursuit team set a new world record in the heats.

Come the final, and the gold medal for their team, the couple embraced, William grabbing Kate as they roared with delight.
