Princess Kate and Princess Charlotte's reaction as they realise their conversation's been caught on camera – watch

The Princess of Wales and Princess Charlotte shared the most heartwarming moment as they attended Wimbledon on Sunday. 

Kate, 44, was joined by her husband, Prince William, and children Prince George, 12, and Charlotte, 11, to watch Italian tennis star Jannik Sinner's victory in the Men's Singles at SW19. 

As is traditional, they watched the tennis action from the Royal Box on Centre Court, with tennis fans Kate and Charlotte soon sharing an animated conversation about the game. 

However, they were soon caught off guard after realising their conversation was being broadcast to everyone watching at home in the official match coverage.

Kate and Charlotte burst into giggles at the unexpected moment, quickly glancing at each other before watching the game again. 

The adorable mother-daughter moment later went viral on social media, racking up 11 million views on X, formerly Twitter.  

Commenting on the footage, one person wrote: "You can tell that Princess Charlotte adores her mother Princess Catherine. They have a lovely mum and daughter relationship 💚💙🎾."

Despite popular belief, Kate and Charlotte did not catch sight of themselves on the "big screen" at Wimbledon. 

On Centre Court, there are famously no big screens, with guests watching the tennis live instead. 

On the Reddit thread r/Wimbledon, someone asked: "Has anyone here been a guest of the royal box?" One person responded: "They have screens in front of their seats!"

Priyanka Chopra, who is married to Nick Jonas, attended Wimbledon last week and filmed content from her day in the Royal Box, revealing the screens in front of her by her feet. 

It means that Kate and Charlotte would have only needed to glance down to see themselves on TV!
