The second in line to the British throne might only be nine years old, but he's already started to take advantage of his royal privileges.
Prince George reportedly did so at school recently when he was crossed by another child, who he proceeded to threaten with his father, Prince William.
The revelation was made by author Katie Nicholl in her book, The New Royals, where she explained that all of the Cambridge children are being brought up with 'sense of duty' and understanding about the monarchy.

She revealed that while George does know that he will one day be King, his parents are trying to let him live a relatively responsibility-free life for now.
Nicholl wrote: "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.
"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'."

While George is now aware of his destiny, royal author Robert Lacey wrote last year in an updated edition of Battle of Brothers that the now Prince and Princess of Wales wanted to tell him at 'controlled moment of their choice'.
The author claimed that the second in line to the throne knew that he will one day be king 'sometime around his seventh birthday.'
His parents reportedly held off on telling him because they wanted to delay a 'life of future royal service and duty' so that George could have a 'normal family upbringing' for as long as possible.

"'William has not revealed to the world how and when he broke the big news to his son," Lacey wrote.
"Maybe one day George will tell us the story himself.
"William's aim as a father was to give his son 'a normal family upbringing', enabling the monarchy 'to stay relevant and keep up with modern times'."

Prince George recently moved up in the line of succession after his grandmother, Queen Elizabeth II, passed away on 8 September.
She was Britain's longest reigning monarch, and at the time of her death, her eldest son, Charles, became King Charles III.
Prince George went on to bravely walk behind the Queen's coffin at her state funeral alongside his parents and sister, Princess Charlotte, 7.
His younger brother, Prince Louis, was deemed too young to attend.
