The surname Mountbatten-Windsor, meanwhile, belongs to all the children and descendants of Queen Elizabeth and Prince Philip.
Stepping out at St George's Hall at Windsor Castle, the Duke and Duchess of Sussex introduced their adorable new bub to the world! Meghan wore a Givenchy dress alongside Prince Harry, who was in a grey suit for the occasion.
Asked what it’s like being a new mum, Meghan said: “It’s magic. It’s pretty amazing. I have the best two guys in the world, so I’m really happy.” She went on to say that Baby Sussex “has the sweetest temperament. He’s really calm.”
Harry then added, “I don’t know where he gets that from!”
“He’s just been a dream,” Meghan said. “It’s been a special couple of days.”
When asked whether the baby takes after anyone, Meghan said: “We’re still trying to figure that out.”
Harry added: “Everyone says babies change so much over two weeks. We’re basically monitoring how the changing process happens over this next month, really. His looks are changing every single day, so who knows?”
When asked about parenting, Harry said: “It’s great. Parenting is amazing. It’s only been two and a half days, but we’re just so thrilled to have our own little bundle of joy.
