As with the birth of the Duke and Duchess of Cambridge's three children, a framed bulletin was placed for fans to view outside Buckingham Palace.
Whilst Meghan and Harry took a considerably millennial approach to their baby announcement - by posting it on social media - it is customary with all royal births to announce the news on an ornate golden easel outside the Queen's residence.
Whilst the presence of the framed announcement seemed normal, eagle-eyed fans have noticed that unlike with Wills and Kate's baby announcements, Baby Sussex announcement was missing signature's from doctors...curious no?
Baby Sussex is yet to be given a name, as it is custom to wait for the Queen to be informed of the name by the parents before announcing it to the public.
