Soooo. Since King Charles III acceded the throne, Prince Harry and Meghan Markle's children Archie and Lilibet Mountbatten-Windsor have technically been entitled to add "prince" and "princess" to the front of their names, which would mean they could match their cousins George, Charlotte and Louis of Wales.
The HRH (His or Her Royal Highness) designation, however, isn't automatic for them, and it's more than likely they won't be granted it—which their parents are reportedly not very happy about.
Despite the children's entitlement to the "prince" and "princess" designations, they are still listed as "Master Archie Mountbatten-Windsor" and "Miss Lilibet Mountbatten-Windsor" respectively in the royal line of succession.
Ultimately, the decision of whether Archie and Lili get to use their princely titles falls to King Charles, their grandfather, who is apparently undecided as it stands—and it all rests on what happens with the Sussexes' big media projects, and how damaging they turn out to be for the Royal Family at large.
"It depends a lot on what happens in the coming months, particularly with Harry’s book and their TV show," a source close to the monarch told Vanity Fair.
These projects refer to a) Prince Harry's upcoming memoir, which in the latest news, has been postponed to 2023, after already having been delayed a number of times in the past; and b) the Netflix docuseries the couple is allegedly producing, which would give us an exclusive behind the scenes glimpse into their Southern Californian life. The latter has still not been officially announced, though at this point it's sort of common knowledge that it's probably happening. (I'm starting to seriously doubt the book will ever come out, though..... But that's just speculation.)
Both projects are, for obvious reasons, not causing a ton of joy among the rest of the Royal Family, who are worried about what could be revealed.
