Prince William rarely kisses or hugs his wife Kate Middleton in public.
But on Wednesday, the Duke of Cambridge was seen kissing his wife in public after taking part in a polo match and raising more than £1 million for charity.
Kate's victorious polo-playing husband raised more than £1 million for a charity supported by The Royal Couple in Windsor.
Thousands of people reacted as their pictures surfaced online.
Prince William is second in line to the British throne. He would succeed his father, Prince Charles, as king.
