King Charles' wife, Camilla, has officially had her title updated to 'The Queen' as the coronation celebrations get underway.
Charles has been acting King ever since the Queen died, but it becomes official in a ceremony at Westminster Abbey today (6 May), where he will be crowned in the first Coronation Service in almost 70 years.
Charles isn't the only one receiving a new title as part of the events, as it was announced that his wife, Camilla, would also undergo a name change.
At first, it was thought Camilla would take on the title of 'princess consort', though that was later changed to Queen Consort.
More recently, however, it was confirmed that she would take on the more simple title, Queen.
The news was first shared when Buckingham Palace revealed the official invitation for the coronation today, which welcomed guests to the "Coronation of Their Majesties King Charles III & Queen Camilla."
Charles and Camilla will officially take on their new roles in the ceremony at 11am, but Camilla's title change has already been confirmed by the official Royal Family website, which shared a picture of Camilla with a caption which labels her as 'The Queen'.
The website goes on to describe Camilla as 'Her Majesty The Queen' - the first time the title has been used since the death of Queen Elizabeth II.
"Her Majesty The Queen (formerly HRH The Duchess of Cornwall) supports her husband, formerly The Prince of Wales, now His Majesty The King, in carrying out his work and duties," the site explains.
"She also undertakes public engagements on behalf of the charities that she supports."
Camilla married Charles in 2005, following her previous marriage to Brigadier Andrew Parker Bowles, with who she shares two children, Thomas Henry and Laura Rose.
Following her marriage to Charles, Camilla has become Patron or President of over 90 charities relating to a range of areas, including health and well-being, promoting literacy, the arts and animal welfare.
After she's crowned at Westminster Abbey, Camilla will return with Charles to Buckingham Palace in ‘The Coronation Procession’ where they will receive a Royal Salute in the Garden of Buckingham Palace from the Armed Forces.
The new King and Queen will then be joined by other members of the royal family on the Buckingham Palace Balcony.
