Prince George, Princess Charlotte and Prince Louis have all made their return to school, with all three currently attending Lambrook School.

Like many children, the young trio all have sweet nicknames for each other and it seems they all have some inside the classroom too.

Despite being members of one of the most-famous families in the world, George, Charlotte and Louis all enjoy a relatively normal childhood, including their school lives.

It was previously noted that George’s classmates refer to him as ‘PG’ – his initials – as well as ‘PG Tips’.

George, 10, appears to enjoy the very-British nickname ‘PG Tips’ – like the well-known tea brand – so much that he wanted to be called it at home too.

Princess Charlotte, eight, is reportedly known to her classmates as the ‘Warrior Princess’, a name that seems fitting with her well-known feisty character.

Royal expert Katie Nicholl has explained that this is due to her being “quite the tomboy”.

Speaking previously to Entertainment Tonight, Ms Nicholl said: “She loves climbing trees and she’s very much an adventurer, she was quite known for her feisty character.”

The Prince and Princess of Wales are known to have their own sweet nicknames for their only daughter, with Prince William having been heard referring to her as “Mignonette” – a French word that means “small and delicate”.

It’s not only the children that have nicknames, as William and Kate are also said to have nicknames for one another.

The Prince is said to sometimes call Kate ‘Babykins’, while Kate refers to him as ‘babe’.

Kate has also been known to poke fun at her husband, having been heard calling him ‘baldy’.
