Prince Louis' adorable nickname revealed as Princess Kate shares rare insight into family life

The video, which announced the end of Kate's chemotherapy treatment, offered a rare glimpse into the Royal Family's private life.

"Lou Bug, you lead the way!" Kate said to Louis, who confidently walked ahead of his siblings and parents.

This was not the first time the public heard Kate using this sweet moniker for her son.

Last year, during The Big Help Out event in Slough, she was overheard using the same nickname.

At the Slough event in May 2023, Kate encouraged Louis as he shovelled sand into a wheelbarrow, saying: "Well done, good job, Lou-bug."

Later, whilst toasting marshmallows, she instructed: "Pop that in the fire, Lou-bug."

The recent video announcing the end of the princess's chemotherapy treatment had several heartwarming moments between Kate and Louis.

It showed Kate and William enjoying outdoor activities with their children in Norfolk.

In one scene, the princess was seen pushing her youngest on a swing.

Another clip captured Louis sitting next to his mother before leaning into the camera with a cheerful "hello, hello".

Prince Louis was also seen throwing a ball up to catch as he led the family walk.

The footage additionally captured moments of the family playing card games together.

In one scene, Louis was shown hugging his father, Prince William.

These interactions highlighted the close bond between Kate and her children, offering a rare insight into their family dynamics.

The Wales family's use of nicknames extends beyond Prince Louis.

Kate has been known to call Princess Charlotte "Lottie" and "poppet," while Prince George has been referred to as "little grape."

Prince William has also used affectionate monikers for his children.

At the 2019 Chelsea Flower Show, he called Charlotte "Mignonette," a French word meaning "small, sweet, and delicate."
