Camilla Parker Bowles made Prince Charles a better man.

According to Harper's Bazaar, the Duchess of Cornwall has been a "force for positive change" in the Prince of Wales' life. The future king is referred to as "the boss," but with Camilla in his life, he has become "a helluva lot easier and happier."

"She's made a massive difference in him," a longtime correspondent told Vanity Fair. "He's much more relaxed now. They are always laughing and chatting, they have great affection and humor between them."

Prince Charles and Camilla have been married for 13 years already, but they are still very much in love. Royal photographer Alexi Lubomirski, Prince Harry and Meghan Markle's official photographer for their engagement and royal wedding noticed this during a photo shoot at Clarence House.

"As soon as they looked at each other, there was a sparkle in their eyes—that’s when the magic happened," the photographer said. "You feel like they are a young couple in love."

A number of their friends described the couple as "a rock" when it comes to their relationship. This is understandable given their history.

Queen Elizabeth II and Prince Philip didn't approve Prince Charles and Camilla's affair. In fact, in a letter addressed to Princess Diana, the Duke of Edinburgh called his own son "silly" for leaving Princess Diana for Camilla.

The Queen also actively disapproved their relationship. In fact, she didn't want to see Camilla in any royal function. According to Tom Bower's book "Rebel Prince: The Power, Passion and Defiance of Prince Charles," the monarch couldn't forgive the Duchess of Cornwall for not giving Princes Charles and Princess Diana the chance to save their marriage.

"She would not condone his adultery, nor forgive Camilla for not leaving Charles alone to allow his marriage to recover," Bower wrote.

Prince Charles and Camilla dated before they met their first spouses Princess Diana and Andrew Parker Bowles, respectively. However, the royals didn't approve Camila because she was not aristocratic enough and they deemed her as a woman with experience.

Prince Charles went on and married Princess Diana. However, he didn't totally get over Camilla. So, their marriage didn't work out.

"I think he had a closer relationship to Camilla than practically anybody. He really really loved her," Penny Junor said. "They had so much in common their brains kind of worked in the same way. I guess he didn't meet anyone else who quite matched up to her."
