The Duchess of York is honoring Queen Elizabeth with a rare throwback photo as she celebrates her historic milestone this weekend.
On Instagram, Sarah Ferguson shared a black-and-white childhood pic of her former mother-in-law, praising the monarch for her "kindness" and "selflessness" throughout the years. She wrote, "How inspiring to see the country united in celebration of your extraordinary dedication to duty and service and steadfastness. You embrace all that you do with kindness and selflessness and this is the finest example. Thank you Your Majesty."
Countless fans added their kind words of support, but several others also took notice of her uncanny resemblance to her great-granddaughter, Princess Charlotte.
