A new book by royal author Robert Jobson suggests that it was Prince Harry, not Meghan Markle, who experienced a "temper tantrum" over the tiara for their royal wedding.

In "Our King: Charles III: The Man and the Monarch Revealed," Jobson delves into the events leading up to the so-called "Tiaragate," where the British press reported an argument within the royal household over Meghan's tiara choice. Contrary to previous reports that Meghan was being difficult or throwing a fit when her tiara choice was denied, Jobson claims it was actually Prince Harry who became "petulant and short-tempered."

In an excerpt obtained by Newsweek, Jobson writes, "On the surface, everything seemed fine. But William and Charles had noticed a difference in Harry, who seemed to be permanently on edge." The stress of the wedding planning appeared to be taking its toll on the couple, with Prince Harry reportedly becoming irritable with staff members.

Jobson adds that Queen Elizabeth II and other senior aides questioned the necessity of Meghan wearing a veil for the ceremony, considering it was her second marriage. However, it was Harry who became upset when Meghan was told she couldn't wear her chosen tiara. Jobson clarifies, "It was not Meghan who threw the tantrum, it was Harry."

In his memoir "Spare," Prince Harry discussed the tiara incident, denying that Meghan was refused an emerald tiara. The duke explained that Meghan was initially offered the Spencer family tiara worn by Princess Diana but later chose an all-diamond tiara made for Queen Mary from the Queen's personal collection.

Harry also recounted tension with the Queen's royal aide, Angela Kelly, who he felt was being deliberately difficult. He considered involving the Queen but worried about the potential confrontation and whose side she might take. He described Kelly as a "troublemaker" and noted that she held all the cards as she was in possession of the tiara.

According to Prince Harry, Kelly eventually arrived at Kensington Palace with Meghan's tiara and a release form. After signing the form, he told her that receiving the tiara earlier would have made their lives easier, to which Kelly responded with a stern look that he interpreted as a warning that their conflict was not over. Kelly has not commented on Harry's claims in "Spare."

Jobson's book also reveals that Queen Elizabeth II worried that Prince Harry's love for Meghan may have "clouded his judgment."
