And the youngest generation of royals also use cute names for their elders. Prince George, Princess Charlotte and Prince Louis are said to know everything about ‘Granny Diana’ and refer to King Charles as ‘Grandpa Wales’. According to the Daily Mail, the nickname Grandpa Wales follows the same format as the Queen used for her grandad George V, who she referred to as Grandad England.

When the royals are in the privacy of their own home, surrounded by just their nearest and dearest, they don’t call each other by their titles.

Many have their own nicknames for each other, with Meghan Markle revealing that she calls her husband Prince Harry, Haz during an unprecedented ‘tour of LA’ interview with James Corden. The Queen ‘s immediate family called her Lilibet and Prince William would refer to her as ‘Gary’ when he was younger as he couldn’t say ‘grandma’.

But when it comes to Queen Camilla it’s apparent that she goes by a different name to the traditional ‘grandma’ or ‘nanny.’ Camilla, who has five grandchildren of her own, plus the Cambridge kids and Prince Harry and Meghan Markle’s Archie and Lili, is referred to as ‘Gaga’. According to the Sun, Camilla told Lady Gaga that her step-children called her ‘GaGa’ when they met during the 2016 Royal Variety Performance.

Shortly after the birth of Prince George, the Duchess told the Daily Mail: “My own grandchildren call me GaGa. I don’t know if it’s because they think I am! It is funny but is still very sweet.”
