Prince Harry has denied long-held claims that he told the Queen's dresser "what Meghan wants, Meghan gets" in an infamous falling out over a wedding tiara.
The Duke and Duchess of Sussex were at Buckingham Palace to view a number of headpiece options to wear ahead of their 2018 nuptials.
Meghan picked out one with emeralds and another with aquamarines, which caused the late Queen to tell her: "Tiaras suit you."
But it was later claimed that she was told she could not wear the tiara, with Harry allegedly responding: “What Meghan wants, Meghan gets”.
The Duke has referenced the unsavoury incident in Spare, saying the Queen’s royal dresser, Angela Kelly, told him that taking the tiara for an appointment with Meghan's hairdresser “couldn't be done”.
According to Page Six, he wrote: “She fixed me with a look that made me shiver. I could read in her face a clear warning. This isn't over."
A separate book by royal correspondent Robert Jobson previously claimed tensions were high in the run-up to the wedding.
He wrote in 2018: “The weeks leading up to the wedding had been far more tense for both Harry and Meghan than most people realised.
“In the build-up to the wedding, says an inside source, he was ‘petulant and short-tempered’ with members of staff.
“Raising his voice on occasion, Harry would insist: ‘What Meghan wants, she gets'."
Prince Harry's memoir, Spare, which was accidentally released early in Spain, includes personal details of his love life, drug-taking and rifts within his family.
The Duke of Sussex also said William is his "arch nemesis" in the book, which is due to be released in the UK on January 10.
Amid the allegations include William confronting Harry in a physical altercation, and upset over a supposed lack of Easter presents.
The book also details how Harry and his brother William would have "extreme mood swings", with their "volatility" often mirroring that of their mother Diana.
It says how Charles found it difficult to predict their behaviour, and how he was often "shocked" at the "level of belligerence" he encountered from his children.
