He's not even a month old, but Archie Harrison Mountbatten-Windsor is already attracting all the A-list visitors.
The latest in the slew of guests to grace Prince Harry and Duchess Meghan's Frogmore Cottage home? None other than tennis superstar, Serena Williams.
And indeed the famed American made sure her visit was documented after sharing a very telling photograph.
Jetting to the UK to see close pal Meghan earlier in May, Serena is understood to have met Archie before she travelled to France where she will compete in the Roland Garros tournament, aka the French Open.
And to make the surprise visit even more exciting for her fans, Serena posted a sneaky photo that hinted at what the trip entailed.
Posing in a rather regal looking room, the tennis star posted the photo to her Instagram alongside the caption: "Je t'aime, @serena ♥️"
While no other royal baby details were given, it all but confirms Serena has paid a visit to Archie, especially considering her close relationship with long-time friend Meghan.
Taking to her former blog, The Tig, Meghan has described the pair's friendship as: "Taking pictures, laughing through the flag football game we were both playing and chatting not about tennis or acting but about good old fashioned girly stuff."
We can only imagine the same conversations remain the norm for the pair these days, with the added bonus of baby talk, of course!

Serena herself has a baby daughter named Olympia, who is one - so there's no denying the pair would have had plenty to chat about these days!
Williams, who is based in the US, also reportedly co-hosted Meghan's glitzy penthouse baby shower back in February.
The estimated AUD$606,000 event was arranged by Meghan's closest friends, including pal Jessica Mulroney who also reportedly paid a visit to baby Archie earlier in May.
Indeed the striking brunette was spotted leaving Pearson International Airport in Toronto with her young daughter Ivy after revealing on Instagram it was their first trip along together.
Markle and Jessica grew close during the filming of television show Suits, which was filmed in Toronto.
Meanwhile, Archie has also had the pleasure of meeting fellow royals including Prince Charles, Prince William, Duchess Catherine and, of course the Queen herself!
As for his cousins Princes George and Louis and Princess Charlotte? Well, if it hasn't already happened, their excitable first meeting will surely not be far off, with the children reportedly "dying" to meet their newborn cousin - cute!
