Prince George reportedly warned his peers at school that his father, Prince William, would one day ascend to the throne - in a royally cheeky retaliation to a schoolyard argument, a royal expert has claimed in an upcoming book about the Royal Family.
The New Royals: Queen Elizabeth's Legacy and the Future of the Crown by Katie Nicholl claims: "George understands he will one day be king and as a little boy sparred with friends at school, outdoing his peers with the killer line: 'My dad will be king so you better watch out.'"
Nicholl is a journalist and royal correspondent for Vanity Fair, and has also served as a royal expert for NBC's Today show, Entertainment Tonight, and the BBC,
The book, which is set to be released at the start of October, also revealed how the eldest son of Prince William and Princess Catherine - as well as his younger siblings, Princess Charlotte, seven, and Prince Louis, four - are being raised.
"They are raising their children, particularly Prince George, with an awareness of who he is and the role he will inherit, but they are keen not to weigh them down with a sense of duty," Nicholl highlighted, per the New York Post.
It is also claimed by the author that Middleton, 40, looks up to Prince Edward and the Countess of Wessex for their parenting techniques.
They have two children in their teens - Lady Louise Windsor, 18, and James, Viscount Severn, 14 - who are the late Queen's youngest grandchildren. They were raised out of the public eye and without HRH titles, the Daily Mail reported.
In 2020, author Robert Lacey published Battle of the Brothers, which was a view into the tense relationship between Prince Harry, 38, and Prince William, 40. Lacey published an updated chapter in 2021 that detailed Middleton and Prince William waited for a "controlled moment of their choice" to tell Prince George he would be king in the future.
The couple had waited until Prince George turned seven, as they wanted their son to have a "normal family upbringing" that wasn't solely focused on a "life of future royal service and duty," Lacey alleged, per the New York Post.
Another reason for the former Duke and Duchess of Cambridge's hesitation in telling Prince George was in part due to "William's unhappiness at the haphazard fashion in which the whole business of his royal destiny had buzzed around his head from the start."
The author further detailed that the new Prince of Wales wishes to "enable the monarchy to stay relevant and keep up with modern times."
