Nicknames, it seems, are a long-standing royal tradition. The late Prince Philip was famously known as “P.P.” among those closest to him, another reference to his initials. A royal insider once explained that these pet names help soften the famously formal atmosphere of royal life, adding a lighter, more childlike touch to family relationships.

Prince George isn’t the only Wales child with a collection of cute monikers. Princess Charlotte is often called “Lottie” by family and friends, and her parents reportedly also use the French nickname “Mignonette,” meaning “sweet” or “delicate.” Prince Louis has his own heart-melting nickname too—one that Kate accidentally revealed during a rare public appearance in 2023.

While taking part in the Big Help Out at a Scouts hut in Slough, Kate and her children were seen toasting marshmallows and making s’mores. As she gently guided her youngest son, Kate let slip her affectionate name for him, saying: “Pop that on the fire, Lou-bugs.”

From “Momma” to “PG Tips” and “Lou-bugs,” these tiny, intimate moments offer a rare glimpse behind the palace curtain—and show that even the future king grows up in a family full of warmth, teasing, and love.
