This A-lister just visited Meghan Markle and baby Archie (and we're calling godmother)

How exciting!

It's hard to believe that Meghan Markle and Prince Harry's baby boy is already three weeks old (though we bet it's been more of a rollercoaster for the two of them than us).

Archie Harrison Mountbatten-Windsor arrived in the early hours of the 6th May, with his name being announced to the world a couple of days later just after his first public appearance.

The baby, who is seventh in line to the throne, has already been visited by the Queen and Prince Philip, Prince Charles and the Duke and Duchess of Cambridge.

While we've no word on who Archie's godparents will be just yet, we do have a few ideas as to who is in the running.

Case in point: Last week a very famous face added to the list of who has visited baby Archie so far and, because of their close friendship with Meghan Markle, we think they're a strong contender for godmother.

According to reports, Serena Williams secretly visited the Duchess of Sussex and her newborn son at Frogmore Cottage along with her husband Alexis Ohanian and daughter Olympia.

It seems that the couple are now letting close friends visit the baby, as Meghan's long-term BFF Jessica Mulroney was also spotted toy shopping with her daughter last week – suggesting she was in the area to meet Archie.

We can't wait to see the official roster of godparents!
