Eagle-eyed royal fans have identified a fleeting cameo from Princess Charlotte in a video celebrating her older brother, Prince George's, 13th birthday.

While Prince George was the central focus of the 18-second clip shared by the Prince and Princess of Wales, the footage also included brief appearances by his siblings. Prince Louis, aged eight, was shown participating in activities like rock climbing and playing on the beach during the family's Easter holiday in Cornwall.

Princess Charlotte, 11, makes a brief appearance in the background of a scene where Prince George, sporting sunglasses, walks along the shore. She can be seen crouching in the sand and playing with her brothers. Social media users expressed delight at the glimpse, noting the importance of sibling bonds.

The video was accompanied by a message from the Prince and Princess of Wales thanking well-wishers for the birthday messages. Earlier, an official photograph of Prince George was released to mark his milestone birthday.

This image, taken by photographer Matt Porteous at Kensington Palace, shows a maturing Prince George, who is set to begin his senior school experience at Eton College in September. This transition marks the first time since 2019 that he will attend school without his younger siblings, Princess Charlotte and Prince Louis.

Prince George's public appearances have been managed to guide him toward public life, with a gradual increase in his official engagements. His last public outing was at Wimbledon earlier this month, and he is not expected to be seen publicly again until he starts at Eton.

The Wales family, including George, Charlotte, and Louis, are currently enjoying their summer holidays. Prince George has concluded his time at Lambrook School in Berkshire, preparing for his move to Eton College, where annual fees exceed £65,000.

Fans have commented on how grown-up Prince George appears in his recent photographs and videos, with some noting his significant height. He was recently seen at Wimbledon with his parents and sister, where the siblings were seen collecting sunhats due to the warm weather. The youngest sibling, Prince Louis, was absent from that particular event.
