• Prince Harry's memoir will be released in 2022, the same year as Queen Elizabeth II‘s historic Platinum Jubilee
  • A royal expert claimed it "upset people" that Prince Harry's book was "coming out in the Queen's Jubilee year"
  • Nick Bullen added that the duke has already ruffled feathers "in a very big way" with his interview with Oprah Winfrey

Prince Harry's upcoming memoir has been causing a stir on social media since he announced it this week, but one royal expert has suggested that the duke may want to reschedule the book's release date.

On Monday, the Duke of Sussex confirmed that he was working on an "accurate and wholly truthful" memoir, which will be released in late 2022 by Penguin Random House.

During an interview with Us Weekly, Nick Bullen, the CEO of Spun Gold who was supposedly dubbed the "King of Royal TV" for his broadcast relationship with the British royal family, weighed in on Prince Harry's upcoming book, pointing out that the release clashes with Queen Elizabeth II‘s Platinum Jubilee.

According to the royal expert, the announcement that he was writing a memoir "undoubtedly sent shockwaves around the place, both at the highest levels of society and just with the average amount on the streets."

"I think it was a couple of [interviews], the first was surely enough, surely the other interview was enough. Let’s draw a line under it … [and] let’s try and start rebuilding from there," the True Royalty TV co-founder and editor in chief added.

Bullen claimed "it upset people" that Prince Harry's memoir was coming out in the same year that the Queen is celebrating her 70th year on the throne, which will be marked with four days of festivities across the U.K. in 2022.

The move "could be seen as disrespectful" on Prince Harry's part, potentially resulting in more conflict since he has already ruffled feathers within the monarchy "in a very big way" since his and Meghan Markle's bombshell interview with Oprah Winfrey in March, according to Bullen.

In a statement announcing the memoir Monday, the publisher said Prince Harry's book will cover everything from his childhood to his present-day life as dad to Archie and baby Lili and as husband to Markle.

"I’m writing this not as the prince I was born but as the man I have become," Prince Harry wrote in a statement obtained by Us Weekly. "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."

A spokesperson for Prince Harry confirmed to People that the royal family wasn't blindsided by the news.

Before the announcement, the duke spoke privately with the royal family regarding the book's publication very recently. He was not required to obtain permission from Buckingham Palace to publish a memoir, the rep added.

When asked for comment on the announcement, Buckingham Palace told People, "Any clarification about the book would be a question for the Duke and Duchess of Sussex."
