Prince William and Kate Middleton are already embracing their new titles.
The royal couple took over the Duke and Duchess of Cornwall titles after William’s father — now King Charles III — ascended the throne following the death of Queen Elizabeth II on Thursday.
“The official account of The Duke and Duchess of Cornwall and Cambridge and the Royal Foundation, based at Kensington Palace,” their official Twitter and Instagram bios read.
The parents of three, both 40, will also become the Prince and Princess of Wales, a title Charles and Williams’ late mother Diana held.
The royal family’s title shuffle comes after the longest-reigning British monarch died “peacefully” at Balmoral Castle at the age of 96 after she was put under “medical supervision.”
Her death marked the beginning of a new era for the House of Windsor, as Charles takes on the throne to become the king of the UK and Commonwealth. Per the Queen’s wishes, Camilla Parker Bowles, his wife, will become Queen Consort.
The now King — formerly known as Prince Charles — said in a statement that his mother’s passing was a “moment of great sadness.”
“We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother. I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth, and by countless people around the world,” the statement read.
It continued, “During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the respect and deep affection in which The Queen was so widely held.”
The entire royal family, including Prince Harry, rushed to Scotland to mourn the loss of the late Queen. Meghan Markle, however, did not make the journey with her husband as she was in Germany promoting the Invictus Games.
Middleton also stayed behind as Thursday was the first day of school for the couple’s children — Prince George, 9, Princess Charlotte, 7, and Prince Louis, 4 — in Windsor, England.
The late monarch is survived by her four children: Princes Charles, Andrew and Edward and Princess Anne, her eight grandchildren and twelve great-grandchildren.
