The British Royal Family is known for its tradition and grandeur, but behind the formal titles and public duties lies a warm, relatable side—evident in the endearing and quirky nicknames that Prince William, Princess Catherine, and their three children, Prince George, Princess Charlotte, and Prince Louis, use for each other. Attending Lambrook School in Berkshire, the royal children lead relatively normal lives, complete with playful nicknames that reflect their personalities and close-knit family dynamic. From “PG Tips” to “Lou Bug,” these monikers, as reported by Mirror, offer a delightful glimpse into the Wales family’s private world.

A Normal Childhood with Playful Nicknames

Despite their royal status, George (10, Year 6), Charlotte (8, Year 4), and Louis (5, Year 1) enjoy a grounded upbringing at Lambrook, where they study, play, and forge friendships like their peers. This normality extends to the nicknames bestowed upon them by classmates and family, which have become a charming hallmark of their school life.

Prince George, second in line to the throne, is affectionately known as “PG” at school, a nod to his title. His classmates took it a step further, dubbing him “PG Tips” after the famous British tea brand. According to Mirror, George loves the nickname so much that he uses “Tips” even at home, embracing the playful connection to his initials. The moniker reflects his approachable nature, allowing him to blend seamlessly with his peers despite his future role as king.

Princess Charlotte, known for her spirited personality, has earned the nickname “Warrior Princess” among her schoolmates. Royal expert Katie Nicholl told Entertainment Tonight that Charlotte’s boldness and adventurous spirit—evident in her love for tree-climbing and outdoor activities— inspired the moniker. “She’s a princess but with a strong, feisty character,” Nicholl explained. “Charlotte’s reputation for being tough and adventurous makes her stand out.” At home, her parents add their own affectionate touches, with William calling her “Mignonette” (French for “small and delicate”) and Kate opting for “Lottie”, a sweet, familiar shorthand.

Prince Louis, the youngest, captured hearts during a May 2025 volunteering event with the Scouts as part of the Big Help Out initiative. While toasting marshmallows, Kate called him “Lou Bug”, a tender nickname that reflects his playful, mischievous charm. The moment, witnessed by royal fans, underscored Louis’s ability to bring joy to public engagements, even at the age of five.

William and Kate’s Own Nicknames

The royal parents are no strangers to nicknames themselves, both within their family and from their pasts. Prince William revealed in a 2007 NBC interview with Matt Lauer that his late mother, Princess Diana, nicknamed him “Wombat” during a childhood trip to Australia. “It started when I was two, after we saw a wombat in Australia,” he shared. “I’m not sure if it’s because I looked like one or something else!” The nickname stuck, becoming a cherished reminder of Diana’s affection.

Princess Catherine, meanwhile, was known as “Squeak” during her school days at St Andrew’s in Berkshire. She explained, “My sister Pippa and I had guinea pigs named Pip and Squeak, so she was Pippa, and I was Squeak.” The name reflects her youthful, down-to-earth personality before she became a global figure.

Within their marriage, William and Kate share playful and affectionate nicknames. At the 2016 Chelsea Flower Show, they were overheard calling each other “darling” and “babe”. Kate has also been known to tease William with “Baldy”, a cheeky reference to his hair loss, while he affectionately calls her “Babykins”. These lighthearted exchanges reveal a couple comfortable in their intimacy, balancing royal duties with a relatable sense of humor.

A Family Bound by Love and Laughter

The nicknames highlight the Wales family’s efforts to maintain a sense of normalcy despite their extraordinary circumstances. At Lambrook, George, Charlotte, and Louis are encouraged to form friendships and engage in typical childhood activities, free from the weight of their royal titles. Their nicknames, whether coined by classmates or parents, reflect their individual personalities—George’s easygoing charm, Charlotte’s fiery spirit, and Louis’s playful energy.

The public’s fascination with these monikers, amplified by posts on X and media coverage, underscores the family’s relatability. “PG Tips is adorable—George owning it is peak royal kid!” one user wrote, while another noted, “Charlotte as Warrior Princess is spot-on—she’s a future queen with attitude!” The nicknames have sparked joy among fans, offering a window into a family that values love and connection.

A Legacy of Affection

The tradition of nicknames extends beyond the immediate family, rooted in the royal lineage. Princess Diana’s influence on William’s “Wombat” moniker and Kate’s childhood “Squeak” tie the present to the past, blending nostalgia with modernity. As the Waleses prepare to relocate from Adelaide Cottage to Forest Lodge, these nicknames will likely remain a cherished part of their family dynamic, grounding them amidst their public roles.

Conclusion

From “PG Tips” to “Lou Bug,” the nicknames of Prince William, Princess Catherine, and their children reveal a family that cherishes humor, warmth, and individuality. These monikers, born from schoolyard camaraderie and parental affection, humanize the royals, reminding us that even future kings and queens share the same playful bonds as any family. As George, Charlotte, and Louis grow, their unique nicknames will remain a testament to their down-to-earth upbringing in the heart of the monarchy.
