Prince Harry and Meghan Markle’s children Prince Archie and Princess Lilibet’s updated titles have been added to the royal family’s official website.

The changes were made early Thursday, with Prince Archie of Sussex being listed at sixth in line to the throne underneath his father, the Duke of Sussex, at fifth in line to the throne.

Princess Lilibet of Sussex, 1, is seventh in line to the throne underneath her older brother, who is 3.

The youngsters were both afforded the titles of Prince and Princess after their grandfather Charles became King following the late Queen Elizabeth II’s death at age 96 on September 8, 2022.

Harry and Meghan’s spokesperson confirmed the decision to use the titles had been sorted for some time, ITV reported.

They said, “The children’s titles have been a birthright since their grandfather became monarch.

“This matter has been settled for some time in alignment with Buckingham Palace.”
