Prince Harry confessed he's 'fed up' during a very revealing chat before the Coronation began, according to a lip reader.
While waiting for the ceremony to start, it's claimed the Duke of Sussex spoke about his struggles with Princess Eugenie's husband.
With Meghan Markle staying at home in California with Prince Archie and Princess Lilibet, Harry was sat next to his cousin's hubby Jack and Princess Alexandra, the cousin of the late Queen.
Before the proceedings began, Harry was spotted having an intense chat with Jack, who seemed to have sympathy with his cousin-in-law.
A lip reader picked up on the moment where Jack asked Harry: "The meeting?"
It's not known what meeting Harry was referring to - and whether it did or did not take place.
Speaking to the Daily Star, the expert said Harry replied: "It's sad. I'm fed up, I've tried talking to him."
It's likely that Harry was speaking about King Charles or Prince William, but there is bad blood with his father and brother.
It's then claimed that the pair had another chat later on while they waited for the new King and Queen to arrive at Westminster Abbey.
The lip reader believes Harry replied to an unknown question from Jack which was referring to Meghan, saying: "No, she's at ..."
While tilting his head, Jack supposedly asked: "And is she?"
Nodding to confirm, Harry added: "It's not ideal."
"If it makes [you] feel any better even I can do it," Jack is believed to have told Harry. "It's not quite the life, is it?"
Harry then shook his head as Jack seemingly said: "I haven't had time for that, not if it's over..."
Then the Duke of Sussex made a very cryptic comment, saying: "It's an eventuality."
The intriguing chat has perhaps thrown up more questions than answers as to the state of Harry's relationship with the rest of the Royal Family.
According to our lip reader, Harry also joked about his quick visit to the UK and revealed what time he was going to be jetting back to California.
With the Coronation falling on Archie's birthday, Harry decided to rush straight back to California to the US to be there for the intimate party.
Our expert said Harry joked about his busy day and told Jack he would be leaving at "about quarter to four", to which Jack replied: "Oh really, when?"
Harry was also believed to have said "that's funny" to his cousin's husband while smiling as they waited for Charles to arrive.
The timings proved to be right as Harry got straight in a car after the Coronation to get a flight back to LA from Heathrow airport.
There was no direct interaction between the duke and his brother or father on the day - but he did make a gesture towards William when he arrived.
As William and Kate proceeded to their seats, body language expert Judi James says Harry performed an "ignore" gesture.
She told the Mirror: "Harry performed what looked like an oddly-times act of ignore or attention diversion as his father, brother and sister-in-law walked in a procession in front of him.
"Harry had been chatting animatedly to Edoardo, jerking a thumb over his shoulder at one point, sharing a giggling laugh that seemed to involve his tongue placed between his teeth, and then doing a mutual, mirrored eye gaze with a matching lip clamp smile to Edo that seemed to signal mutual sympathy or empathy.
"Harry was looking up as Charles, William and Kate arrived to walk past but after looking at his father, Harry turned his head to speak to Eduardo again in a very odd way at a crucial point in the ceremony when all eyes and attention were on Charles and William's arrival."
