Prince William and Prince Harry inherited a particular trait from their mom, Princess Diana.

According to royal expert Robert Jobson, Princess Diana was "quite difficult" for Prince Charles to handle. Her two boys, the Duke of Cambridge and the Duke of Sussex have the same attitude.

"I think there is some similarities to Diana. Both William and Harry can be a bit hotheaded, there's no doubt about that," Jobson told Express.

"They can be a bit difficult and Diana on many occasions had been quite difficult for the Prince to deal with in that marriage," he added.

In his upcoming book "Charles at Seventy: Thoughts, Hopes and Dreams," he hinted about how Prince William and Prince Harry had some tension with Prince Charles. He added that it's inevitable in a family.

"But look, anybody who's had a teenage son or teenagers to deal with will know that there will be moments of friction between parents and children. That’s just an inevitability of growing up and going into manhood, that’s just life," he continued.

In the same book, Jobson shared some moments when Prince Harry became "petulant and short-tempered" with the members of the staff. The stressful moment happened during the royal wedding preparations.

"Raising his voice on occasion, Harry would insist: 'What Meghan wants, she gets,'" Jobson wrote.

Prince Harry and Prince William are also known for their dislike to the press. In fact, the Duke of Sussex blamed the media for Princess Diana's death.

"I think one of the hardest things to come to terms with is the fact that the people that chased her into the tunnel were the same people that were taking photographs of her while she was still dying on the back seat of the car," Prince Harry told BBC in 2017 to mark Princess Diana's 20th death anniversary.

"She had quite a severe head injury but she was very much still alive on the back seat. And those people that caused the accident, instead of helping, they were taking photographs on the back seat, and then those photographs made their way back to news desks," he added.

In related news, just recently, Prince William and Kate Middleton were praised for their "calming vibe." The Duke and Duchess of Cambridge visited Centrepoint and many were impressed with how they connect to the people.

They are warming people," Gareth Bradbury, 24, said. "They have an almost calming vibe that puts you at ease. It was easy to talk about anything."
