He may be just a few weeks old but Archie Mountbatten-Windsor has already met one of sport's biggest stars.

Serena Williams dropped by Frogmore Cottage in Windsor to see the new arrival and spend time with his mum, Meghan Markle, last week. The tennis ace brought her husband Alexis Ohanian and their 20-month-old daughter Olympia, according to the Daily Mail. While there, she even posed for photos in what appears to be an ornate-looking room in Meghan and Harry's home, sharing it to Instagram. Serena made the stop before she travelled on to Paris to prepare for the French Open. She and Meghan go back years, having first met through a celebrity charity soccer game. Serena was a guest at the royal wedding in Windsor last May and also hosted Meghan's high-profile baby shower in New York City earlier this year. She's thought to be in the running to be named as Archie's godmother -  but she's not the only friend of the Duchess who's been to visit since the royal birth earlier this month. Meghan's old friend, Canadian stylist Jessica Mulroney, is understood to have flown in with her five-year-old daughter Ivy last week and could well get the nod. Ivy was one of Meghan's flower girls when she got married.
