Prince Harry revealed the comment his wife Meghan Markle made which allegedly began her infamous bridesmaid dress row with sister-in-law Princess Kate, it has been reported.
During the run up to the Duke and Duchess of Sussex' royal wedding in May 2018, Harry claims Meghan brazenly told Kate she must have "baby brain because of her hormones" - and the comment wasn't well-received.
Kate gave birth to her third child, Prince Louis, just a month before Meghan and Harry's big day and was heavily pregnant at the time of the fitting.
During all three of her pregnancies, she suffered from hyperemesis gravidarum - excessive nausea and vomiting caused by a hormone imbalance.
In the book, Harry reportedly recounts how Kate was upset - but Meghan apologised and explained that is how she speaks to her friends, the Sun reported in an extract they obtained.
But Harry said William "pointed a finger at Meg", then allegedly blasted: "Well, it's rude, Meghan. These things are not done here."
To which Meghan responded: "If you don't mind, keep your finger out of my face."
This remark reportedly left Meghan upset - especially as she was reportedly warned she wasn't close enough to Kate to make a remark about her hormones.
The infamous row featured in countless news reports before Meghan and Harry quit the UK, and the Duchess referenced the incident in her Oprah interview.
A source who has seen a copy of the book ahead of the publication told the Mail : "In the book Harry says that there was a discussion about the timing of the wedding rehearsal and the flower girl dresses and Kate was very upset.
"Meghan said that Kate must have ''baby brain'' because of her hormones.
"It caused a huge row because Meghan was told that she wasn't close enough to her sister-in-law to discuss her hormones and it wasn't the way people spoke to each other within the Royal family.
"The book makes clear that Meghan felt the fall-out wasn't her fault, but it doesn't exactly make her look very good either."
The first signs of trouble between the pair were broadcast at the time - with claims of a tearful row at a bridesmaid dress fitting.
Sources initially claimed Meghan had made Kate cry. Three years later, Meghan refuted those allegations, insisting to Oprah Winfrey that it had been 'the other way round'.
"She (Kate) was upset about something, but she owned it, and she apologised. And she brought me flowers," said Meghan.
"There wasn't a confrontation and I don't think it's fair to her to get into the details of that because she apologised, and I have forgiven her.
"What was hard to get over was being blamed for something that not only I didn't do, but that happened to me."
Following the incident, reports broke out that Meghan had made Kate cry - and two weeks later William and Kate came for a summit to Harry’s home.
The book reports that Kate admitted that she had made Meghan cry - but the Sussexes were angry that Kate and William's press team had not corrected the reports, it is said in the book.
Kate is described as being flustered and William evasive, as Harry alleged he knows what was really happening, it adds.
Spare also reports that Willam and Kate allegedly admitted that whilst Harry and Meghan were touring Australia, they had gone to have dinner with Camilla and Charles and may have let it slip that there had been a row between the two couples
According to the book, Harry put hand to mouth, Meg was frozen and the foursome went their separate ways.
Kensington Palace and Buckingham Palace have so-far declined to comment on the leaked claims from Harry’s book which emerged five days before the explosive tell-all autobiography Spare is due to be published.
An extract from the book was leaked by the Guardian - before the Sun found a copy on sale in a Spanish bookstore despite the tight pre-launch security.
In it, Harry claims he was physically attacked by his brother in a row and that it was him and the Princess of Wales who encouraged him to wear a Nazi uniform to a fancy dress party 2005
Harry wrote: "William called me another name, then came at me. It all happened so fast. So very fast. He grabbed me by the collar, ripping my necklace, and he knocked me to the floor.
"I landed on the dog’s bowl, which cracked under my back, the pieces cutting into me. I lay there for a moment, dazed, then got to my feet and told him to get out.”
Other revelations from the book include how the brothers's nicknames are Willy and Harold and how their father pleaded after the Duke of Edinburgh’s funeral: "Please, boys. Don’t make my final years a misery.”
Harry claimed William had come to his cottage in the grounds of Kensington Palace to discuss "the whole rolling catastrophe” of their relationship and struggles with the press, but was already “piping hot” when he entered.
William went on to call Meghan "difficult”, "rude” and "abrasive”, claims Harry - before allegedly saying he was trying to help and Harry replying: "Are you serious? Help me? Sorry – is that what you call this? Helping me?”
The duke said the comment further infuriated William who reportedlyswore while stepping toward him - prompting Harry to move to the kitchen.
Harry writes that he gave his brother a glass of water and said: "Willy, I can’t speak to you when you’re like this.”
He then claimed William called him another name before he "came at me” with it all happening "very fast” before the alleged physical confrontation.
The duke writes that William urged him to hit back, referencing fights they had as children, but that he refused and William left before returning and apologising.
Harry writes that William told him he did not need to tell "Meg” about this and added: "I didn’t attack you, Harold.”
The duke says he did not tell Meghan straight away but did ring his therapist, and later admitted to his wife what happened when she saw the "scrapes and bruises”.
Meanwhile, US website Page Six said sources reveals how Harry puts some of the blame for his Nazi uniform scandal on William and Kate.
He tells how the 20-year-old phoned the couple to ask them whether he should chose a pilot’s uniform or a Nazi one for the fancy dress party and William and Kate said the latter, and both howled with laughter when he and tried it on for them.
Harry, then 20, sparked outrage and was widely condemned when a photograph of him in the uniform complete with swastika ended up on the front page of a newspaper.
He admitted in his Netflix tell-all: "It was probably one of the biggest mistakes of my life.”
Amid the claims, ITV released a new trailer for Tom Bradby’s interview with the Duke, which will be broadcast on Sunday night.
Bradby challenges Harry on "invading the privacy of your most nearest and dearest without permission”.
Harry replies: "That would be the accusation from people that don’t understand or don’t want to believe that my family have been briefing the press.”
The duke is also seen saying: "I don’t know how staying silent is ever going to make things better.”
ITV News at Ten presenter Bradby – a friend of Harry’s – says: “Wouldn’t your brother say to you, ‘Harry, how could you do this to me after everything? After everything we went through?’ Wouldn’t that be what he would say?”
Harry replies: "He would probably say all sorts of different things.”
This story is based off a translated version of Prince Harry’s book Spare.
