William’s cousin Peter Phillips and famed jockey Frankie Dettori also joined Kate in the crowd to cheer the Prince on.
Royal fans took to social media to express their admiration for William in his polo gear, with one tweeting: “The future of the monarchy looks hot, I mean bright!”
Another commented: “He is super hot, wow! Those arms, legs, abdomen…And we wonder why Catherine always has that huge smile. King energy.”
A third added: “Prince William has always been super fit and has this body shape, look for early water polo photographs and you will see for yourself.”
A fourth wrote: “The future king is FIT. Wow. That body really is something else.”, while a fifth commented: “Prince William…HOT!”
Another tweeted: “Prince William (Aka his Royal Hotness) looking fit AF during his charity polo match today.”
Kate and William were also seen indulging in some PDA after the game as they kissed each other sweetly on the cheek while she presented her husband with his trophy.
The Princess also affectionately squeezed his arm as the couple have been notably appearing more relaxed together at recent events.
A huge fan of sports, Kate laughed and cheered from the sidelines as she drank some champagne and mingled with charity representatives, who are set to receive around £1million in funds raised by the match.
Earlier in the week the Princess went to Wimbledon for her first visit to the tournament this year, where she sat in the Royal Box with Roger Federer.
The eight-time Wimbledon champion was honoured for his career at a special ceremony after he announced last year he was retiring from the sport.
However sitting behind them was a surprising guest, Nazanin Zaghari-Ratcliffe, who was invited by Andy Murray to sit in the Royal Box and watch him play after she told him watching him win Wimbledon in 2016 helped her through her Iranian prison ordeal.
