Prince Louis brought more charm to the 2024 carol service in another way. He had been trusted with one of the most important surprises of the evening. Kate wanted Princess Charlotte to be delighted by an unexpected ballet performance during the concert, so she told Louis about it two weeks beforehand and made him promise to stay quiet. When the day arrived, Kate proudly revealed that her youngest son had indeed kept the secret. She shared how he had pleaded that morning to be allowed to tell Charlotte, admitting that he was bursting to say it. Even so, he waited until the moment arrived, allowing his sister to discover the surprise herself.

Now in its fifth year, Together at Christmas continues to be held at Westminster Abbey and hosted by the Princess of Wales. Prince William and other senior royals attend, and the evening features carols sung by the renowned abbey choir, along with readings and musical performances by guests such as Hannah Waddingham, Dan Smith, Kate Winslet and Chiwetel Ejiofor. Ahead of this year’s service, Kate released a message reflecting on the meaning of the season. She wrote that Christmas invites people to reach out to one another with generosity, understanding and hope, and that the service offers a moment of togetherness. Her words echo the very sentiment that made Prince Louis’s small handwritten note last year feel so moving, a reminder that even the quietest gestures can hold the deepest warmth.
