"I think she's wonderful for King Charles. They know each other so well that he can trust her," royal expert Angela Levin dished.
"It's very hard when you're a monarch to trust anybody because things leak, we've got lots of examples of that. She makes him laugh. She's really helping him handle his feelings about Harry, and she does an awful lot of territory that he's not the least bit interested in, like domestic violence and all that sort of thing. But he has his own space. She doesn't want to be in the spotlight, so she's there for him. I think he's a different man," she added.
Levin continued: "He's working hard, and he seems much more popular, and he's smiling a lot now. And I think she's a terrific Queen. It was just like Prince Philip, she wants to be there and always help him."
Her Majesty became Britain's first Queen Consort in over 70 years when Queen Elizabeth II died and Charles acceded to the throne. Although there are still numerous commentators who felt "cheated" that it wasn't Diana, Princess of Wales, becoming queen last year, the former Camilla Parker-Bowles has won praise for her approach to the role.
The Queen was also the subject of what some called "hateful attacks" by Prince Harry in his memoir, Spare. In the book, which was released nearly one year ago, the fifth in line to the throne described his stepmother as "dangerous" and someone willing to "leave bodies in the street" in a quest to receive good PR as a public figure.
This is said to have greatly angered the King, who is fiercely protective of his second wife, but others point out how His Majesty also has a soft spot for Harry as his youngest child.
Although the Queen is now sympathetic to her husband's plight in having to deal with "Prince Harry drama," this wasn't the case in recent months.
"Camilla is the power behind the throne!" a source spilled to a publication before adding how the Queen told the King to "man up" and stop "being guilt-ridden for not being a good dad to Harry as a boy" in October.
That allegedly "nasty" disagreement caused "their biggest-ever fight and left their marriage on the rocks," RadarOnline.com reported at the time. Insiders went on to spill how the Queen was working behind the scenes to ensure Charles III's reign was not defined by Harry and Meghan Markle.
