Queen Elizabeth II, Princes William, Charles Joked About This At Royal Garden Party

The British royal family can be playful too.

Express shared an archive footage taken from the Queen Mother's 101st birthday in August 2001 featuring Queen Elizabeth II, Prince Charles and Prince William. In the clip, the trio was joking about a game between the Prince of Wales and Duke of Sussex.

"The last thing I remember was William saying 'don't shout at me,'" Prince Charles recalled, laughing.

"In slightly less polite language," Kate Middleton's husband said.

"Impolitely, I bet," Queen Elizabeth II responded jokingly.

"There was a lot of family shouting going on," Prince William added.

The clip is one of the footages to be featured in the documentary titled "Queen of the World," which will be aired on ITV next week. In the same documentary, Prince Harry also revealed his true feeling for the monarch. According to the Duke of Sussex, he panics at Her Majesty's presence.

While speaking with a group of hospitality professionals from the Caribbean who are spending time at the palace, Prince Harry asked them if they had already met the Queen. The duke also left them with a few words of advice if ever they encounter the monarch.

"You guys have spent way more time in Buckingham Palace than I ever have - and you’ve only been here two weeks," Prince Harry asked. "Have you bumped into the Queen yet? If you suddenly bump into her in the corridor, don't panic. I know you will. We all do!"

In related news, Prince Charles' interview in which he denies his affair with Camilla has resurfaced. According to the future king, he tried to be faithful to Princess Diana and insisted that the Duchess of Cornwall was just a friend.

"But all I can say is there's been so much speculation feeding on every other speculation that becomes bigger and bigger, and all I can say is there is no truth in so much of this of this speculation and Mrs Parker Bowles is a great friend of mine," Prince Charles said.

However, according to a body language expert, based on his actions, the royal was annoyed, anxious and impatient when asked about his infidelity and marriage with Princess Diana. According to Judi James, Prince Charles also shows signs of guilt.

"His anxiety, impatience and 'hide' rituals told another story," James said. "At times he even opted for the kind of verbal swerve that we normally associate with politicians who want to avoid answering questions or telling the truth."
