Princess Charlotte may only be 4 years old, but she’s already got an enigmatic draw to her. We’ve learned some interesting facts about the little princess in recent years: We know that she likes cheesy pasta and unicorns; we know she loves horseback riding; and we know that her parents each have a nickname for her. While Kate Middleton calls her Lottie, Prince William calls her Mignonette. In case those names aren’t adorable enough, we’ve learned of another one. This time, it’s Charlotte’s nursery school nickname — and it suits her quite well.
Charlotte may be getting in with the big kids at Thomas’s Battersea School in London, but before she started attending the school this fall, she went to Willcocks Nursery School. There, Charlotte was known by the nickname “Warrior Princess.” She earned the nickname “because of her love of the outdoors and her feisty and outgoing character,” according to royal reporter Katie Nicholl. It seems the fearless, fun-loving princess left quite her mark on her nursery school and her classmates.
