Princess Eugenie and her sister, Princess Beatrice, have both kept their kids out of the royal spotlight, but on Tuesday, Oct. 15, Eugenie shared some rare photos of her youngest son, Ernest, to mark a milestone birthday for mom Sarah Ferguson, the Duchess of York.
"Happy birthday to my beautiful mumma," she penned the Instagram tribute, which contained a carousel of unseen family photos to celebrate Ferguson's 65th birthday. The post included two snaps of little Ernest dressed in a casual green sweatshirt and jeans as he spent time with his grandma in a manicured garden.
