The Royal Family has changed Camilla's title on the website - to update it from Queen Consort to Queen.
Royal commentator Omid Scobie pointed out the change on Twitter, as he posted: "Queen Consort no more. The official Royal Family website has just updated Camilla’s title to The Queen."
It comes as King Charles and Queen Camilla made their first appearance of coronation day – travelling the short distance from their Clarence House home for final preparations at Buckingham Palace.
Crowds in The Mall cheered as they caught sight of Charles and Camilla being driven in a state limousine between the royal residences.
They are due to leave the palace at 10.20am and travel in a procession to Westminster Abbey where first the King and then the Queen will be anointed and crowned by the Archbishop of Canterbury, Justin Welby.
Inside the ancient abbey, the church buzzed with noise as the congregation filed in and took their seats hours before the ceremony was due to start.
A smiling Dean of Westminster in his vivid red clerical robe was seen hurriedly carrying the holy oil for the anointing down the length of the abbey from the altar through the quire, clutching the precious ornate silver vessel in both hands.
Crowds had been building up in the capital since dawn with the streets around the procession route – The Mall, Admiralty Arch, Trafalgar Square, Whitehall and Parliament Square – thronged with people.
The coronation ceremony will end at 1pm and the newly crowned King and Queen will begin the procession back to Buckingham Palace in the gold state coach.
Some 4,000 sailors, soldiers, aviators and other military personnel from across the UK and the Commonwealth will accompany Charles and Camilla on their return procession. There will be more than 1,000 route liners from the Army, RAF and Royal Navy.
Charles and Camilla are expected to enter Buckingham Palace through the centre arch at 1.33pm.
They will receive a salute from the military in the palace gardens at 1.45pm, and then at about 2.15pm they will be joined by members of the royal family on the palace balcony to watch the flypast.
