This is the moment Prince George tells his dad, Prince William, that he's "too hot" while at the Wimbledon final wearing a suit as temperatures soared to the high 20s.
The Duke and Duchess of Cambridge brought their oldest son to day 14 of the tennis tournament at the All England Lawn Tennis and Croquet Club, Wimbledon.
In an adorable clip shortly after the trio arrived, Prince William can be heard asking if George "is okay" and he replies saying he's "too hot".
Kate Middleton then appeared to comfort George by reassuring him they mostly sit in the shade during the matches.
The eight-year-old youngster appeared all smiles while he sat in the Royal Box with his family as Nick Kyrgios battled Novak Djokovic for the title.
George was dressed smartly in a navy suit and tie, sparking concerns from royal fans as temperatures reached 28C during the day.
One wrote online: "Poor little Prince George at Wimbledon for the men’s singles final wearing a jacket and tie! 30C temperatures!"
Another added: "With heat warnings in place for all esp kids and elderly – why are @KensingtonRoyal trotting out George donned in a suit, shirt and tie @Wimbledon?"
A third commented: “Feel a bit sorry for Prince George having to sit through the Wimbledon men’s singles final. It could go on for hours and in this heat too!!!”
Yesterday, George, dressed in a dashing suit and tie, arrived without siblings Charlotte or Louis but could be seen engrossed in the captivating showpiece.
While Kate, a patron of the All England Club, and William greeted a group of military personnel who are working as stewards at the championship, young George, eight, was asked who he was supporting.
The youngster appeared too shy to answer so William looked at him and whispered: “Djokovic” before adding: “We’ll see how long it lasts. He’ll support the winner.”
Watching from the Royal Box, George was snapped covering his head with his hands as he looked on nervously during the early stages of the fierce contest.
Plenty of people have taken to Twitter after Kyrgios' outburst at his box, which appeared to include some choice swear words.
With the pair tied at one set each, George appeared to have a somewhat confused and scrunched look on his face as he looked in the direction of the Australian.
His outburst prompted Marion Bartoli, former Wimbledon champion, to comment on BBC Radio 5 Live: "This just has to stop. Kyrgios can't keep doing this - this is the final of Wimbledon. The umpire has to step and do something."
One tweeted: "The little Prince George was not impressed with all the swear words from Nick. His expression got me laughing so hard earlier."
Another agreed, adding: "These constant foul-mouthed tirades by Nick Kyrgios at #WimbledonFinal right in front of the Royal Box and young 8-year-old Prince George are a disgrace. Hope he gets fined big time."
