Prince William refuses to repeat King Charles’ jealousy as Kate Middleton captivates royal crowds: experts

Kate Middleton has landed on her feet as the monarchy's brightest star, and Prince William is clearly enjoying the view.

"It's not just about duty," British broadcaster and photographer Helena Chard told Fox News Digital.

"Prince William is not only proud, but he is smitten.

He watches Princess Catherine and lights up.

After more than a decade of marriage and three children, he is still completely enchanted by her." "Few marriages have deepened in public admiration the way theirs has," Chard said.

"They have achieved something very difficult — they have carved out a private life that works, and a public life that works.

That balance is a great success." PRINCE WILLIAM, KATE MIDDLETON ARE READY TO LEAD THE MONARCHY, SOURCES SAY: 'THANK GOD THEY’VE GOT EACH OTHER' Chard's comments came shortly after former BBC royal correspondent Jennie Bond told The Mirror that the Prince and Princess of Wales have emerged as a power couple for the royal family, with Kate as its crown jewel.

"William and Catherine definitely have the wow factor that Diana had — and which spawned Di-mania," Bond told the outlet.

"People today are equally mesmerized by the new Princess of Wales, so tall, so elegant and so chatty, but William just seems to purr with pride that his wife is such a star." Christopher Andersen, author of "Kate!," agreed.

WATCH: KATE MIDDLETON IS THE MONARCHY'S SECRET WEAPON: AUTHOR "The British people adore Kate in the same way they adored Princess Diana, the daughter-in-law she never met," Andersen told Fox News Digital.

"But rather than be jealous of his wife the way King Charles was jealous of Diana's popularity, William is more than content to let Kate shine.

In fact, there are times when he is perfectly happy to bask in her reflected glory." "Kate has been William's rock for a quarter-century, and vice versa," Andersen continued.

"What they have is the real thing.

And I think Kate's cancer battle gave them a whole new perspective on life and a renewed appreciation of each other.
