On the day his book, “Spare,” is released, Prince Harry will appear on a late-night show.

The Duke of Sussex will be making an appearance on “The Late Show with Stephen Colbert” to discuss his memoir, “Spare,” on Tuesday. The show announced Prince Harry’s appearance on Twitter.

The Late Show tweeted, accompanied by a photo of Prince Harry’s book cover:

“Prince Harry, The Duke of Sussex, will join @StephenAtHome for an exclusive late-night interview on #Colbert to discuss his new memoir, #Spare. Watch only on @CBS & @paramountplus on Tuesday, January 10th at 11:35/10:35c.”

Another tweet from the show included a clip of Colbert discussing Prince Harry’s appearance on the show for his book.

Stephen Colbert said:

“On Tuesday, we have actual royalty because Prince Harry is gonna be sitting right there to talk about his new book ‘Spare,’ It’s either a gripping tell-all about the royal family or a book of handy bowling tips. Tune in to find out.”

He concluded:

“Stock up on corgis and steal a priceless cultural treasure from one of your colonies because ‘The Late Show’ is going imperial, okay.”

The promo for Prince Harry’s upcoming appearance on the late-night show elicited mixed reactions from viewers.

One commented:

“Why do all famous people think we’re interested in their problems and issues? News flash, we have the same ones without the money and advantages.”

Another added:

“Nope, unless you plan to call him out on all the inconsistencies.”

A third person wrote:

“Oh Stephen, you’re better than this.”

Another commented:

“Oh nooo Stephen! Whyyy!?!”

A fifth commenter said:

“Hard pass on this.”

Prince Harry makes his first appearance on the show, but it is his second late-night appearance. The Duke of Sussex was previously seen on “The Late Late Show with James Corden,” according to Deadline.

Aside from his CBS appearance to promote his book, Prince Harry has two interviews: one with ITV’s Tom Bradby and one with Anderson Cooper for “60 Minutes.” Both will be broadcast on Sunday.

In addition, Prince Harry will appear on “Good Morning America” for another interview with Michael Strahan. Their entire interview will be aired on Monday.

They discussed his book and how he viewed Prince William as his “beloved brother” and “archnemesis” in “Spare.” Prince Harry also told Strahan that he needed to tell the truth in order to bring peace to his family.

He said:

“Ultimately, what this all comes down to is, I don’t think that we can ever have peace with my family unless the truth is out there.”
