Just seen the news about Baby Harkellina.
So can we take it that's the 'confidential reason' confirmed.
A spokesperson for Meghan and Harry said: 'We can confirm that Archie is going to be a big brother.
'The Duke and Duchess of Sussex are overjoyed to be expecting their second child.'
So that wording leaves the surrogacy question out there, doesn't it?
ETA Oh nice phrasing Daily Mail - I see what you did there:
'It comes just months after the Duchess of Sussex, 39,
said she lost her second child in an article for the New York Times.'
