Prince Charles is delighted that his mother, Queen Elizabeth II, confirmed his wife’s future title.

On Sunday, the monarch renewed the pledge she made on her 21st birthday to devote her entire life to the service of the U.K. and the Commonwealth. She also remembered the death of her father, King George VI, which elevated her to the throne. However, it was her comments about Camilla, Duchess of Cornwall, that stirred headlines.

"When, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support that you have given me; and it is my sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service," said the 95-year-old.

On Wednesday, a source close to the Prince of Wales revealed that he couldn’t be happier.

"Charles is over the moon that his mother has given her seal of approval," an insider told Us Weekly on Wednesday. "It’s a dream come true."

The queen herself noted the importance of having a supportive partner by one’s side as a royal.

"I am fortunate to have had the steadfast and loving support of my family," she said. "I was blessed that, in Prince Philip, I had a partner willing to carry out the role of consort and unselfishly make the sacrifices that go with it. It is a role I saw my own mother perform during my father’s reign."

The source noted that Camilla is prepared for the responsibilities that come with her title.

"Camilla had to work twice as hard as any other royal to gain popularity and shed her reputation as the wicked stepmother – the woman who stole Charles from Diana," the source told the outlet.

It took years for many in Britain to forgive Charles, whose admitted infidelity and long-time links to Camilla torpedoed his marriage to Princess Diana. The mother of Princes William and Harry died in a Paris car crash in 1997 at age 36, five years after her messy, public split from Charles, now 73.

But the public mood has softened since Charles married Camilla Parker Bowles in 2005.

The duchess, 74, has taken on roles at more than 100 charities, focusing on a wide range of issues including promoting literacy, supporting victims of domestic violence and helping the elderly.

Her down-to-Earth style and sense of humor won many over, and it also softened Charles's image. The Prince of Wales appears more relaxed, if not happier, during his royal outings and he waits for his chance to reign.

Charles has long made it clear that he wants Camilla to be known as queen when he ultimately succeeds his mother on the throne. In his message congratulating his mother’s long years of service, Charles thanked her for her support.

Back in 2019, True Royalty TV launched a documentary titled "The Real Camilla," which aimed to give an intimate look at the royal’s life, as well as insight into her enduring love and partnership with Charles. The film followed Camilla for a year as she embarked on official tours, as well as chronicled her private downtime in Scotland. It also featured interviews with those closest to her, including her nephew Ben Elliot.

At the time, producer Juliet Rice told Fox News Digital that Camilla would make an ideal Queen Consort for Charles.

"She’s an incredibly good listener," said Rice. "She and Prince Charles support each other brilliantly. Even during public appearances, they have a real synergy together. It’s rather lovely to see. And they have a real laugh together. It’s quite something, doing the job that they do. And they do it brilliantly together. They’re a really strong double act."

"She’s also very discreet," continued Rice. "Everyone in the film said she’s absolutely his rock. She’s also very down-to-Earth. She’s a real British countrywoman. She loves her dogs, she loves her horses, she likes her gardening and she’s incredibly relatable for that reason. She’s not grand in any way. And she’s also a real giggle. She and Charles have great fun together, which is one of the best ingredients for a good marriage."
