When their grandfather the King took the throne six months ago, Harry and Meghan’s children became prince and princesses.
Nevertheless, the Sussexes used Lili’s title for the first time in public on Wednesday when they announced their daughter’s christening.
The line of succession page on royal.uk now refers to Archie and Lili as Prince Archie of Sussex and Princess Lilibet of Sussex.
Before, they went by the names Master Archie and Miss Lilibet Mountbatten-Windsor.
The brothers, who each advanced one position after the passing of the late Queen, are currently sixth and seventh in line for the throne.
The choice to use the titles had been “decided for some time in alignment with Buckingham Palace,” according to a spokesperson for Harry and Meghan.
When their grandpa became king, the children have been entitled to their titles by birth.
According to Buckingham Palace, this issue has been resolved for a while, the spokesperson stated.
Lili, a 21-month-old baby girl, was christened in a private ceremony on Friday at the Sussexes’ California family home in front of her grandma Doria Ragland and her famous godfather Tyler Perry.
The Prince and Princess of Wales, the Queen Consort, and the King were apparently invited but did not go.
Prior to Wednesday’s christening announcement, Charles is believed to have been aware that the Sussexes planned to refer to their daughter as Princess Lilibet and that there had been discussion on the subject.
When Charles became king, Archie and Lili automatically became a prince and a princess in accordance with the title regulations established by King George V in 1917.
