And while fans wait for the royal couple to officially introduce Baby Sussex, it seems we may have already caught a glimpse of the seventh in line to the thrown.
Francesca, who looks after Harry and Meghan's fan account @harry_meghan_updates on Instagram, believes she can see the little one moving inside Meghan’s tummy during her visit to the the National Theatre in January this year.
At the time, the former Suits star would have been about six months pregnant.
”We saw your little foot or hand," read a comment on the page.
"You're a very active little one."
Can you see Baby Sussex?
