We are less than a week away from Prince Harry’s bombshell memoir release date on January 10th.

Royal family fans are getting a taste of what will be discussed in his memoir, “Spare.”

It’s looking like a DOOZY for King Charles III and his brother, Prince William.

In the leaked extract from “Spare” obtained by The Guardian, Harry claims King Charles III told the late Princess Diana his work was “done” after his birth in 1984.

Harry was born on September 15, 1984.

His father celebrated the “wonderful” news by telling his ex-wife, “Now you’ve given me an heir and a spare- my work is done.”

Obviously, this is a reference to the royal family’s line of succession.

King Charles III was made king following the death of his mother, Queen Elizabeth III.

Once KCIII passes, Prince William will take over the throne and become king followed by his first-born, Prince George (9).
