Princess Catherine’s Alleged 3-Word Joke About Prince Louis and Her Art History Background

During a state visit from French President Emmanuel Macron and his wife Brigitte on July 8, 2025, Princess Catherine made a charming remark that linked her art history background to her role as a mother. The event, held at Windsor Castle, marked the first French state visit to the UK in over 17 years and was attended by King Charles III, Queen Camilla, and the Prince and Princess of Wales.

While viewing an exhibition from the Royal Collection, Kate made a playful comment upon seeing a portrait of King Louis XIV, saying, “I should know.” This referenced both her youngest son, Prince Louis, and her art history studies at the University of St Andrews.

Kate’s education gave her a sharp eye for historical portraits, enhancing her appreciation for such exhibits. Though Prince Louis wasn’t present, his cheeky personality has been well-documented at past events like Trooping the Colour 2025, where he delighted crowds with his playful behavior.

Louis also joined the royal family for the 80th anniversary of Victory in Europe Day, mimicking his older brother in a humorous gesture that won over royal watchers once again.

Previously, in 2023, Louis stole the show at The Big Help Out by joining in outdoor activities, including operating a digger with his father and roasting marshmallows with his siblings.

During that event, Kate affectionately called him “Loubugs,” revealing her warm maternal side, which shines even during formal occasions.

William and Kate later shared highlights from the state visit on Instagram, emphasizing the strong diplomatic ties between the UK and France.
