Prince Harry's best-selling memoir Spare is coming out in paperback in October, less than two years after the book was first released.

In the run-up to the publication of the tell-all memoir in early 2023, Prince Harry drummed up publicity and took part in a few interviews. In mid-January 2023, he made his debut on The Late Show with Stephen Colbert, where they discussed his life and whether the prince watches The Crown.

The Duke of Sussex replied that he does in fact watch the Netflix hit, which follows the Royal Family up until the wedding of the now King and Queen. Harry even admitted to fact-checking elements of the programme, which released last year its final season detailing Diana's tragic death.

While he started off the chat "relaxed", Harry "lost control" after this question, according to body language expert Judi James.

The expert reckoned Harry wasn't as relaxed as he pretended to be, feeling some discomfort over the discussion, hiding behind smiles and gags with the audience.

Speaking exclusively to The Mirror, Judi said: "This chat-show appearance was Harry at his best: seemingly relaxed and funny, he clearly adored being in the spotlight and marinated in the noisy audience support like a man who had finally come face-to-face with his own fanbase."

The expert added: "Colbert is quick but Harry was often quicker and presented himself as the cool royal who was prepared to spill any amount of tea if he was asked the right questions.

"He seemed un-shockable right up to this point where he was asked about The Crown and despite his facial expressions retaining the aura of being a chilled, down-to-earth fun guy, his hands and leg movements told a contrasting story of unease and of losing control of the interview."

Judi further explained: "Asked 'You watch The Crown?' Harry gets a twinkle in his eye immediately to signal he knows where this one is going.

"His mouth hikes up at the corner in a signal of colluded humour and he feigns surprise to appease the host by opening and shutting his mouth and letting out a dry laugh.

"This looks like he is pretending to be put on the spot as it makes the gag better. But in reality he turns to his new friends the audience to share the joke with them and his cheeks puff out in a smug smile.

"The lower half of his body is looking much less smug though. His body language leakage signals suggest genuine discomfort at this point. He rubs his hand on his leg and then crosses his legs in a barrier ritual that suggests he'd secretly prefer to change the subject."
