While the Duke and Duchess of Cambridge were sitting in the stands watching the epic tennis match, Kate was given a cute little surprise gift by none other than tennis superstar, Stan Smith. Smith gave Duchess Catherine a tiny pair of his iconic Stan Smith Adidas sneakers that had his signature on them as well as a cute little personal touch: "To Louis". 

A family that loves tennis

Even though at this point Prince Louis isn't quite ready to try his hand at the sport yet, with his family's interest and love of tennis and his big brother Prince George already getting private lessons from Roger Federer, we can see how the little royal would follow in his family's footsteps! 

Duchess Catherine gives the trophy

Duchess Catherine also had the honour on Sunday to present the winner of the Men's Singles final, Novak Djokovic, with his trophy. She looked stunning in a light blue dress and cute nude heels. Prince William also looked handsome while out on an afternoon date with his wife.
