That would mean Princess Diana would have to curtsy to her sons, William and Harry.
William was just 14 at the time of his parents' divorce and promised his mother to restore her title.
'Don't worry Mummy, I will give it back to you one day when I am king,' Paul Burrell recalls William as saying.
Since Diana's death, Burrell has been distanced from the royal family. He claims he has not spoken to William or Harry since their mother's passing.
Burrell frequently releases intimate details about what he claims went on 'behind palace walls.'
