Archie Mountbatten-Windsor is a new big brother! Both of his parents Duchess Meghan and Prince Harry retained their royal titles in his birth certificate as they were still senior members of the royal family but his younger sister was born in the new era.

Lilibet Diana's Birth Certificate

When the Duke and Duchess of Sussex stepped down from their posts as senior members of the royal family, many wondered if they would relinquish their titles. Others have stepped down in the past but kept their royal titles like beloved Princess Diana or sex trafficker Jeffrey Epstein's close friend Prince Andrew.

Now we know, as TMZ has just released royal baby Lilibet Diana's birth certificate. When Archie was born his mother was listed as "Rachel Meghan Her Royal Highness The Duchess of Sussex" but on Lilibet's California birth certificate she is listed as "Rachel Meghan Markle" with no royal title.

On the other hand, Harry's first name is listed as "The Duke of Sussex" and his second is "His Royal Highness" as his last. Buckingham Palace had previously issued a statement stating "The Sussexes will not use their HRH titles as they are no longer working members of the Royal Family."

Harry's HRH title was even removed from his mother Princess Diana's Exhibition a few weeks ago. The Royal Collection Trust explained why "Lent by HRH The Duke of Cambridge and HRH The Duke of Sussex" was changed to "Lent by HRH The Duke of Cambridge and The Duke of Sussex." The Trust explained, "Due to an administrative error, for which The Royal Collection Trust was responsible, the labels were incorrect and will be updated."

It seems as he has been permitted to retain the HRH title for his daughter's birth certificate. Prince Harry runs all of the formalities through "the firm" and his grandmother Queen Elizabeth so he must have been allowed to use it. 

Neither of their children was given their birthright titles of Prince and Princess.
