A new photo of Prince Archie and Princess Lilibet has been circulating online, showing the siblings with their backs to the camera as they admire Lilibet’s Ariel-themed 4th birthday cake.

The charming shot highlights their shared red hair — a feature linked to the Spencer family and one their grandfather, King Charles, is said to dislike.

A Special Disney Celebration

The image appeared in the documentary The Happiest Story on Earth: 70 Years of Disneyland — A Special Edition of 20/20, released on September 21.

The film featured Prince Harry and Meghan Markle sharing childhood memories from Disneyland while also documenting their own family’s trip to the park in June for Lilibet’s birthday.

For the occasion, the Sussexes ordered a two-tier cake topped with a figure of Princess Ariel, Lilibet’s favorite Disney character.
