The Queen no longer goes by her childhood nickname Lilibet after the passing of her husband Prince Philip, who was the last person to use it.
It was fondly adopted as a moniker by the Queen's grandparents and parents during her early childhood when she struggled to pronounce her name, calling herself " Lilibet " instead.
She would often sign off letters with the shortened version of Elizabeth, including in a thank you note addressed to her grandmother Queen Mary, the Daily Star reports.
