Prince George is said to have used a cheeky remark to get one over on his classmates by warning them 'my father will be king so you better watch out', according to a royal biographer.

Prince George is said to have warned his classmates at school 'my father will be King so you better watch out', according to royal biographer who reported the cheeky exchange in her new book.

Katie Nicholl claims Prince George, nine, once used a cheeky quip to get one over on his friends at school by telling them his 'father will soon be King' before warning them 'so you better watch out' it has been revealed.

The Wales youngster is now second in line to the throne in royal succession, following the death of Queen Elizabeth II. Prince Charles has become King Charles II and his father Prince William has taken on the new title of Prince of Wales, until it's his turn to ascend to the throne.

And in her new book, The New Royals, Katie writes, "[William and Kate] 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'."

Prince George and his siblings, Princess Charlotte, seven and Prince Louis, four, who pushed his dad's hand away in hilarious clip, recently started their new school together, as students at Lambrook in Berkshire.

The family recently re-located to Windsor from Kensington Palace and their old school St Thomas' in Battersea.

But it's thought Prince William and Kate Middleton, Princess of Wales are said to have told George he would be King one day several years ago.

Author Robert Lacey previously wrote in his book that George found out about his future role "some time around his seventh birthday".
