If there’s one thing we know about the British royals, it’s that they love their nicknames, and apparently, Prince William, 41, and Kate Middleton, 41, have some playful monikers they use for one another, in addition to their pet names.
Sure, the Prince of Wales loves calling his other half “Babykins,” but it turns out he also has a cheeky nickname that was inspired by a joke from the late Queen Elizabeth II: “The Duchess of Doolittle.”
