Prince William and Camilla Parker Bowles’ first meeting happened unexpectedly when the former was 15 years old.

In the book Battle of Brothers, author Robert Lacey revealed that Prince Charles informed his sons that he was traveling from Eton London to hang out with his friends.

But to the heir to the throne’s shock, Prince William surprised him. But it was the Duke of Cambridge who was even more surprised when he saw Camilla with his dad.

Prince Charles informed Camilla that Prince William was there, and her initial reaction was bolt. But the Duchess of Cornwall immediately got back to her senses, powdered her nose, and put on a brave face. She smiled at Prince William and the rest was history.

According to the author, Prince William and Camilla’s first meeting went on smoothly. But it was evident that Prince Charles’ wife was a little bit tensed because it was the Duke of Cambridge that carried the conversation the entire time.

Prince William and Camilla talked about horses, hunting, and polo. He also asked about Camilla’s son, Tom, who happens to be Prince Charles’ godson.

After talking to Camilla for approximately 30 minutes, Prince William asked permission from his dad to leave so he could watch movies. The Duke of Cambridge was so relaxed and calm but after he left, Camilla trembled like a leaf.

Lacey said that just a few months after Princess Diana’s demise, Prince William already decided that he would meet Camilla because he knows how important she is to Prince Charles.

Meanwhile, Camilla met Prince Harry much later than Prince William but their encounter was also relaxed. Lacey also said that the meeting between Camilla and Prince Harry was planned.

“It was over tea again - this time at Highgrove a month or so later in the company of Tom and Laura Parker Bowles, Camilla's two slightly older children, with whom William and Harry had already spent some time the previous Easter,” Lacey said.

After the meeting, Camilla, reportedly, noticed that Prince Harry stared at her curiously. But this didn’t take away from the fact that they had a blast during their first meeting.

Today, Prince William and Prince Harry have both developed a close relationship with Camilla. And they also defended her amid claims that she’s an evil stepmom.
