PRINCE Harry was moaning as he prepared to watch his father’s crowning glory, according to a lip reader.
He was apparently lamenting his life, muttering: “I’m fed up with the way they treat me.”
The Duke of Sussex made the comment to Jack Brooksbank — his cousin Princess Eugenie’s husband — as they took up their positions in the third row, our expert said.
He was back in his £11million pad in Montecito, California, today after dashing home to celebrate son Archie’s fourth birthday having been in the UK for just over 24 hours.
Only 15 minutes after the Coronation’s 1pm finish at Westminster Abbey, Harry got into a BMW and was driven 20 miles under police escort to Heathrow.
There, he boarded a flight to Los Angeles to be reunited with wife Meghan, 41, Archie and 23-month-old daughter Lilibet.
They were said to have enjoyed a “small, intimate gathering” and a lemon cake baked by the Duchess of Sussex using fruit from their garden.
It emerged yesterday that the King raised a glass to toast Archie’s birthday at a family lunch after the Coronation — a tribute to the grandson he has barely seen.
Sources said Harry, 38, was invited to the private palace gathering but declined.
Most of the Royal Family are believed to have “breathed a sigh of relief”.
But the King, 74, was “genuinely quite disappointed that he didn’t stay”, according to reports.
It is unclear who Prince Harry was referring to when he told Mr Brooksbank that he was fed-up.
Following the controversy over his best-selling but highly-damaging book, Spare, it could have been aimed at other senior members of the Royal Family.
It is also possible his remark was aimed at the British media amid his ongoing High Court legal battles with sections of the Press.
From the exchange, trained lip reader Jeremy Freeman also picked up on the glum-looking Duke saying: “It’s not an ideal situation.”
Mr Brooksbank apparently replies: “If I can make you feel any better, and even I can do it. It’s not the quiet life, is it?”
Harry, fifth-in-line to the throne, appears to shake his head before saying: “They don’t care.”
Brooksbank adds: “I haven’t time for that, not if it’s over…”
Harry adds: “It’s an eventuality.”
The lip reader also picked up on King Charles grumbling while wearing the St Edward’s Crown on the Buckingham Palace balcony.
Mr Freeman said Charles — while the monarch was waving at tens of thousands of adoring fans — told his wife Camilla: “I can’t see a thing with this crown. I can’t look up.”
The Queen seemingly replied: “I can’t see anything either, my crown will fall off.”
Mr Freeman claimed that earlier, the anxious monarch had groaned, “We can never be on time” as he waited in the Diamond Jubilee State Coach in the rain ahead of his Coronation.
Millions were glued to the TV on Saturday as Harry sat among the Royal Family for the first time since criticising Charles, Camilla, William and Kate in his memoir.
His relationship with his brother, the Prince of Wales, remains deeply strained.
The pair are not believed to have exchanged any words before or after the ceremony.
Yesterday’s royal reception began with Prince William, 40, standing to congratulate his father on his date with destiny.
The King thanked everyone in return and raised a glass to grandchildren Prince George, nine — who also served as a Page of Honour — Princess Charlotte, eight, and five-year-old Prince Louis.
He then toasted “those that weren’t there” before poignantly wishing absent grandson Archie a very happy birthday “wherever he was”.
A source said: “It was apparently a very sweet moment.”
The Royal Family then tucked into canapés, including mini broad bean and tarragon Coronation quiches, and were offered champagne.
The gathering was followed by a private family drinks party at Windsor Castle.
