Prince Harry and Meghan Markle are set to celebrate their son Archie's birthday on Friday 6 May, with the eldest of the couple's two children turning three. Meghan, 40, and Prince Harry, 37, tend to keep their young son out of the spotlight, having only shared a handful of snaps of him over the last three years. The couple, who are also parents to eleven month old daughter Lilibet, will be celebrating Archie's birthday over in California, where they now permanently reside after stepping down as senior royals back in 2020.
