The Duchess of Cornwall will be honored with the title as she is now more accepted in the Royal Family than when she married Charles in 2005, according to the real expert Dickie Arbiter.
At that time, "the feelings were very high," with royalty and the public still accepting the death of Princess Diana, which occurred in 1997.
The real commentator said: "I think you'll find 13 years after the Duchess of Cornwall is accepted by the royal family."
"Prince William and Prince Harry are happy with her and happy for her father and there is no reason for us to be either."
"Diana does not forget, but the monarchy advances and evolves".
Mr. Arbiter said that the monarch's wife uses the title of Queen Consort.
She added: "When the Prince of Wales becomes King, which may still be a long time away, she will become the Queen Consort.
"There is no other title for the king's wife."
It occurs after the royal family previously insisted that Camilla would be known as the Princess Consort when Charles ascends the throne.
But earlier this year, all references to the Princess Consort title were removed from the Clarence House website, fueling speculation that Charles' wife will be Queen Camilla.
Over the years, public opinion has changed, since Camilla has made real commitments and works of charity.
Mr. Arbiter said: "When she goes out on commitments, many people go out to see her and the Prince of Wales.
"She is a good communicator, she does not want to be the center of attention.
"She is very happy that the Fab Four have the spotlight, but she is there to support the Queen and she is the Prince of Wales' support for her husband."
And Camilla is assuming an increasingly important role in the Royal Family.
Earlier this month, the Duchess of Cornwall joined His Majesty on the balcony of the Foreign and Commonwealth Office to see the commemoration service at the Cenotaph.
And Camilla held a central place in the family photos published to commemorate Charles' 70th birthday on November 14.
In a lavish party to celebrate the milestone of the birthday of the throne, the queen referred to the support role of Camilla when he gave a very personal speech to Charles and wished his son a happy birthday.
The Queen said: "During his 70 years, Philip and I have seen Charles become a champion of conservation and the arts, a great charitable leader, a dedicated and respected heir to the throne to be compared to anyone in history, and a wonderful father. " .
"Above all, supported by his wife Camilla, he is his own man, passionate and creative."
