Princess Diana's perceptions of Queen Camilla's loyalty and King Charles' deep feelings for her have proven accurate, according to royal expert Jennie Bond. As Queen Camilla celebrated her 77th birthday on July 17, Bond, a former BBC royal correspondent, reflected on the dynamics of the royal couple's relationship, especially in light of King Charles' recent cancer diagnosis.

"I think that whereas Charles was rather jealous of Diana's success, he could not be more proud of Camilla, who has come to this role late in life and without the safety net of an adoring public," Bond told OK! "These difficult few months will have made his love even deeper." She noted that Camilla's dedication to her royal duties has significantly strengthened her bond with King Charles.

Bond also highlighted Princess Diana's insightful comments about Camilla's loyalty. "I think part of it is because she so much wants the man she loves to be proud of her. But it must also be so gratifying to have earned widespread approval, even affection, from a public who once ganged up against her as the 'other woman' who made Diana so unhappy," she continued. "I think Diana was absolutely right to tell me that Camilla was 'loyal' and that Charles' love for Camilla was stronger than any marriage he might ever have made."

King Charles' jealousy of his late wife's popularity was well-documented. Princess Diana often overshadowed Charles at public engagements, with media coverage focusing on her fashion and charm. In her 1995 interview with BBC's Martin Bashir for "Panorama," Diana acknowledged the complications that arose from the media attention. "No, not particularly, because with the media attention came a lot of jealousy, a great deal of complicated situations arose because of that," she said.

Prince Harry echoed these sentiments in his memoir "Spare," describing his father's jealousy towards Diana. "Pa might have dreaded the rising cost of maintaining us, but what he really couldn't stomach was someone new dominating the monarchy, grabbing the limelight, someone shiny and new coming in and overshadowing him," Harry wrote, referring to Charles' decision not to support his wife, Meghan Markle, financially because there was not "enough money."

Harry drew parallels between his mother and Meghan, noting their similar qualities. "So much of what Meghan is, and how she is, is so similar to my mom. She has the same compassion, she has the same empathy, she has the same confidence. She has this warmth about her," he said.

Bond's reflections on the royal couple come as Camilla steps up her royal duties amidst King Charles' health concerns. Her dedication and the public's growing approval have played a crucial role in solidifying her position within the royal family. Despite the initial backlash she faced as the "other woman," Camilla has worked diligently to earn respect and admiration.

Princess Diana's observations about Camilla's loyalty and Charles' unwavering love have been validated over time. The challenges the couple has faced, including public scrutiny and health issues, have only served to deepen their bond. "Charles could not be more proud of Camilla," Bond reiterated, emphasizing the king's admiration for his wife.

Camilla's journey from being perceived as a divisive figure to becoming a respected queen consort illustrates the complexities of royal life and relationships. Her commitment to her role and to King Charles has won over many critics, demonstrating the resilience and strength required to navigate the intricacies of the British monarchy.

As King Charles and Queen Camilla continue to fulfill their royal duties, the insights shared by Princess Diana and echoed by royal experts like Jennie Bond provide a nuanced understanding of their relationship. The public's evolving perception of Camilla underscores the importance of loyalty and dedication in the face of adversity.
