At the King's Coronation yesterday (May 6), there were plenty of memorable moments, from the crowning itself to a sweet gesture between Princess Charlotte and her younger brother Prince Louis as they arrived at Westminster Abbey holding hands.
And now it seems the young Princess has done it again and is melting hearts of Coronation Concert viewers with another touching gesture.
This time, it was for her older brother, Prince George.
During the concert at Windsor Castle, their father Prince William took to the stage to give a speech dedicated to the King and the key workers in Britain.
When the Prince of Wales appeared on stage, eight-year-old Charlotte perked up immediately, looking excited and gesturing to her brother to look at their dad, pointing over to the stage.
George, amusingly, didn't look quite as impressed to see his dad up there.
The cute sibling moment was also spotted by numerous fans on social media, who branded it 'heartwarming'.
One person tweeted: "Whatever your thoughts on the Royal Family, you can't fail to find Princess Charlotte joyfully pointing out her father to her brother when he appeared on stage incredibly heartwarming. A reminder that the key word in Royal Family is Family."
Another said: "Aww Prince George and Princess Charlotte."
While a third wrote: "Aww, Charlotte so excited to see her daddy on stage! She's like 'look George!' George is like 'whatevs'."
Someone else posted: "Charlotte's face when her daddy came out. Bless her."
Others joked she was 'waking' her brother up to get him to pay attention.
The two young royals shared several other great moments during the Coronation concert.
The pair could be seen singing along as Katy Perry sang Roar and waving their flags and young Charlotte is also have said to 'dabbed' during the show.
Their mum, Kate, also was 'shining' throughout and fans loved how 'proud' she looked as her husband took to the stage for his speech.
She was spotted laughing at his cheeky joke and beaming at him from the Royal box.
