Kate's book, created in partnership with the National Portrait Gallery, will be available in UK bookshops and online from May 7, one year since the project was first launched and a month before Meghan's book is published.
The Duke and Duchess of Cambridge, who announced earlier today they'd be starting their own YouTube channel, shared a video which flicked through the pages of the book to their Instagram, with the caption: 'Coming this Friday #HoldStill2020'.
