Princess Diana's biographer Andrew Morton thinks that one of Princess Diana's siblings could be chosen as a godparent for Meghan and Harry's baby son Archie Harrison Mountbatten-Windsor.
Speaking on Yahoo UK's 'The Royal Box,' Morton says: "It’s very interesting that Sarah McCorquodale was the reckless one, the wild one, the one who was expelled from school, very much in the kind of Harry mould.
"And then Jane, the elder sister was very much the sensible one and she was the one who read a lesson at the wedding you may recall.
"So it will be very interesting which Spencer they ask to be a godparent, will they go wild or will they go steady?
Historian Anna Whitelock believes that Harry's cousin Zara Tindall and their A-list friends Serena Williams and George Clooney could also be chosen.
She says: "I think we’ll see a blend of the celebrity and royalty in the choice of godparents."
