The three siblings were seen hanging red paper loops with their handwritten names on a symbolic Connection Tree, representing the value of community and meaningful moments shared together. As the evening went on, the tree filled up with dozens of paper chains, each signed by guests as they departed.
However, fans were most intrigued by a close-up photo showing the children’s contributions — particularly Prince Louis’ rarely-seen and unexpectedly mature handwriting.
The royal trio were later photographed holding candles alongside fellow attendees. Once again, viewers pointed out how much Louis has grown, with many noting his strong resemblance to George and Kate.
