A royal expert has revealed who Meghan Markle and Prince Harry "certainly" chose as one of the godmothers for their son, Master Archie Harrison.

Archie Harrison Mountbatten-Windsor was baptised on Saturday, July 6 in the private chapel at Windsor Castle, surrounded by family and his parents' close friends. And while the details of his christening (including who had been named godparents) had been kept private, that hasn't stopped the speculation about who Archie's godmothers and godfathers may be. Royal expert Omid Scobie told Yahoo UK's The Royal Box that the Duke and Duchess of Sussex had been including "friends from the past" among the godparents for their two-month-old son. He went on to add that one of Meghan's sorority sisters whom she recently attended Wimbledon with - Lindsay Roth and Genevieve Hillis - was "certainly" made a godmother. He said:

"They're really including friends from the past. With Meghan, she had her friends Lindsay Roth and Genevieve Hillis at the christening. "They're all sorority sisters from Northwestern University and have stayed tight-knit. And one of those is certainly one of the godparents."

It had been previously reported that the identities of the godparents would be kept a secret as they were private citizens, and not people in the public eye. The Duke and Duchess of Sussex were thought to have decided on this, which led them to face a lot of criticism. However, Scobie added the request for privacy actually came from the godparents. He explained:

"I think there's been a lot of confusion about who requested this privacy. Because from the outside it looks like Harry and Meghan didn't want to share that information with the world. "But actually the real story is that some of the godparents themselves didn't want their names out there."

He also said that Serena Williams shouldn't be "ruled out" as a possible godmother for Archie - even though she was unable to attend the christening due to playing at Wimbledon. He added:

"I actually looked into the rules here. Can you be a godparent and not attend the christening? "And as long as someone attended on her behalf, she could be a godparent. I wouldn't rule her out altogether."
