Prince Harry seemed "un-shockable" during an appearance on The Late Show With Stephen Colbert, until the conversation turned to The Crown.

The hit Netflix show has released its final series, which shows the months leading up to the tragic death of Harry's mother Princess Diana. Diana and her boyfriend Dodi Fayed died in a car crash in Paris in August 1997 while their driver, Henri Paul was fleeing the paparazzi. Henri also died in the crash.

Sitting down for an interview with Stephen as he promoted his debut memoir Spare, Harry was asked if he watches The Crown. While he started off the chat "relaxed" he "lost control" after this question, according to body language expert Judi James.

During the chat, Harry said: "Yes I have actually watched The Crown, the older stuff and the more recent stuff." Stephen replied: "Do you fact check it while you watch it?"

Harry gave a cheeky grin and acted as if he was jotting notes down. After a pause, he said: "Um, yes I do actually." He was met with raucous laughter from 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?' he 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's secretly prefer to change the subject."
