Many of us have been given nicknames from our family members in our childhood that just sticks into our adult years.
Even members of the royal family have endearing names for one another, from Prince Harry calling the Duchess of Cambridge 'Cath' instead of 'Kate', to the late Prince Philip being referred to as 'PP'.
Similarly, Prince William has an adorable little nickname for his daughter, six-year-old Princess Charlotte, which is very different to the one used by his wife Kate.
The sweet name was first revealed when Wills and Kate and their children attended the Royal Chelsea Flower Show, as Kate had helped to design a garden for the show.
William called out to Charlotte whilst they were playing on the swings, asking her to come and give him a push, but instead of saying 'Charlotte', he calls for 'Mignonette.'
The French word is said to mean "small, sweet, and delicate" or "cute," and is pronounced like min-yon-ett.
Meanwhile, Kate has her own affectionate name for Charlotte, revealing during a trip to Northern Ireland in 2019 that she calls her daughter Lottie.
During an official royal visit, Kate met mum Laura-Ann and her son, who later took to Instagram to share their conversation.
"She asked how old Bertie is, and I said he is four and she said, 'Oh, he's the same age as Lottie.' She calls her Lottie," Laura-Anne wrote.
But while its onl'y natural her family give her pet names, it turns out Charlotte could be set to inherit a rare royal title which has only been used seven times in royal history - Royal Princess Charlotte.
