• Prince Harry's memoir is still coming out in the fall of 2022, a report says
  • His book allegedly contains new revelations that should worry the royal family
  • Prince Harry collaborated with ghostwriter J.R. Moehringer for his memoir

Prince Harry's memoir will include content that should make the royal family "nervous" when it comes out this year, a report has claimed.

Despite reports that it has been delayed, the Duke of Sussex's $20 million book is still due to be released in the fall of 2022 and contains revelations that he's never spoken about before, Page Six reported, citing multiple unnamed sources. International Business Times could not independently verify this information.

One New York publishing source described the highly anticipated memoir as "juicy."

Another anonymous publishing insider claimed of the upcoming book, "There's a lot of new stories in there about the past that Harry has not spoken about before, about his childhood … there is some content in there that should make his family nervous."

However, Prince Harry reportedly made sure not to include anything critical or disrespectful toward his grandmother, Queen Elizabeth II.

Prince Harry's reps have not yet commented on the report.

The 37-year-old royal is working with ghostwriter J.R. Moehringer for his memoir, according to the outlet.

The Pulitzer winner wrote memoirs for Andre Agassi and Nike co-founder Phil Knight. Moehringer also published his own autobiography, "The Tender Bar," which was adapted into a movie directed by George Clooney and starring Ben Affleck.

Rumors recently surfaced that the release of Prince Harry's book was postponed after it was not included in publisher Penguin Random House's list of upcoming releases.

"We think it's being delayed because it hasn't been included on a list of the upcoming books on the marketing list. So some are saying that it has been pushed back," 9Honey reporter Natalie Oliveri said on "Today Extra." "There are suggestions that the royal family has potentially intervened here. I think that's a bit unlikely, perhaps, we're going to be seeing a really big launch later this year."

However, a spokeswoman for Transworld, part of Penguin Random House, told The Sun Sunday, "We don’t put every book on the list so there is nothing to be extrapolated from that."

Prince Harry's memoir will follow his previous sensational claims about the royal family.

In his and Meghan Markle's tell-all interview with Oprah Winfrey in March 2021, he claimed his father Prince Charles and brother Prince William are "trapped" within their roles.

He and Markle also alleged that an unnamed member of his family raised concerns over the complexion of their unborn child, sparking racism allegations against the royal family.

In a statement in July 2021, the Duke of Sussex said he will give an "accurate" and "truthful" account of his life in his memoir.

"I'm writing this not as the prince I was born but as the man I have become. I’ve worn many hats over the years, both literally and figuratively, and my hope is that in telling my story—the highs and lows, the mistakes, the lessons learned—I can help show that no matter where we come from, we have more in common than we think," Prince Harry said.

Proceeds from the memoir will be donated to charity, according to a press release.
