Why Prince George, Charlotte and Louis might never call King Charles THIS nickname again

Prince George, Charlotte and Louis might never call their grandpa King Charles by this name again after recent title changes.

The Wales kids experienced a change to their family name when their parents Prince William and Kate Middleton transitioned from the Duke and Duchess of Cambridge to the Prince and Prince of Wales, following King Charles' ascent to the throne.

And as a result of Charles going from Prince to King, as he was next in line to the throne in royal succession following the death of Queen Elizabeth II, he lost one of his titles - the Prince of Wales.

Reports have claimed that Prince George, 10, Princess Charlotte, eight, and Prince Louis, five, have called Charles 'Grandpa Wales' for many years, but now he's no longer the Prince of Wales it's likely that his grandchildren will have to use another name.

He's not the only member of the Royal Family who has a nickname - Prince George fondly called the late Queen 'Gan-Gan' and Queen Camilla's grandchildren call her 'Gaga'.

And Prince George and Princess Charlotte have an adorable nickname for their brother Prince Louis, which is "Lou Lou" and Prince George is known as "PG" or "Tips".

While Prince George has an adorable nickname for dad William - he reportedly calls him "Pops".

It's not yet clear what new name the Wales kids call King Charles, whether they simply call him Grandpa or another name combination like Grandpa King or Grandpa Charles.

But during the Wales' family volunteering over the Coronation weekend, a comment from Prince Louis suggested that King Charles could now just be called "Grandpa".

When someone got some white paint in their hair, Prince William pointed out, "He has white hair now" to which Prince Louis added, "Just like Grandpa".
