Little prince’s bigger book

PRINCE Harry has said that he won’t write a sequel to his blockbuster tell-all “Spare” — but sources told Page Six there is buzz that he could potentially pen a bonus chapter to be included in the book’s paperback release.

Said an insider: “Prince Harry is already planning to add at least one new chapter — and possibly more — to the paperback version of ‘Spare’ out later this year or early next when the hardcover sales have ended.”

The source added that “readers are eager to know [Harry and his wife, Meghan Markle’s] feelings about the royal backlash they have suffered after the airing of their Netflix doc and the publication of ‘Spare.’ ”

Random House released the hardcover version of the book on Jan. 10, and Harry himself narrates an audio version. However, details of a further paperback release have not yet been announced. The book’s publisher did not respond to a request for comment and a rep for Harry huffily denied he’d be including any new chapters in a future edition, telling us via email when we asked for comment, “There is no story because that’s not true.”

The book has shattered sales records as the fastest-selling nonfiction book of all time.

Then again, the Californian Duke of Sussex certainly has more than enough material left to add to the publication. He has said that his initial draft of the book came in at a whopping 800 pages, but that it was whittled down to about 400.

Harry has intimated he wouldn’t publish a follow-up out of respect for his brother, Prince William, and dad, King Charles III. He reportedly said in an interview last month, “It was 800 pages and now it’s down to 400 pages. It could have been two books, put it that way. And the hard bit was taking things out.” Harry also added of the material that did not make it: “I don’t think they would ever forgive me.”

Then again, there certainly would be even more to write about after the book’s whirlwind release and even more royal controversies.
