The duchess shared a never-before-seen photo of a newborn Lili—and a video that shows her and Harry busting a move in the delivery room—in honor of the princess’s big day.

On June 4, 2025, the couple's daughter, Lilibet “Lili” Diana Mountbatten Windsor, now Princess Lilibet of Sussex, celebrated her 4th birthday, with her mom sharing new photos of her to mark the occasion. Lilibet was born in Santa Barbara, Calif., in 2021, two years after her big brother, Archie Harrison, in May 2019.
