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.

The Duchess of Sussex shared new images of her and Lilibet cuddling by the ocean and as a newborn Meghan Markle is celebrating her daughter Princess Lilibet's fourth birthday with a heartfelt tribute — and some new photos.

Lilibet became entitled to use the title princess upon the King's accession to the throne due to the late Queen Elizabeth's grandfather, King George V. She does not use a HRH status as it was decided that Harry and Meghan would not be allowed to use their HRH titles when they stepped down as working royals.
