Queen Elizabeth Was 'Surprised' Meghan Markle Wore White Wedding Dress, Upset With Harry's Behavior: Book

Queen Elizabeth II was "surprised" Meghan Markle chose a pure white wedding dress for her royal wedding to Prince Harry, a new book has claimed.

Markle looked stunning in an off-the-shoulder Givenchy dress designed by Clare Waight Keller when she tied the knot with Prince Harry on May 19, 2018. The stark-white gown featured a bateau neckline and structured three-quarter sleeves. She completed her wedding day look with Queen Mary's bandeau tiara and a silk tulle veil that paid homage to the Commonwealth and all 53 of its countries.

However, the late Queen reportedly "had reservations" about the color of Markle's bridal gown because her marriage to Prince Harry wasn't her first, Vanity Fair royal correspondent Katie Nicholl claimed in her new book, "The New Royals: Queen Elizabeth's Legacy and the Future of the Crown."

"The Queen was surprised that Meghan wore pure white on her wedding day," an anonymous source told Nicholl for the book, according to an excerpt published by the Mail on Sunday.

"Perhaps it's a generational thing, but she believes if you've been married before, you wear off-white on your wedding day, which is what the Duchess of Cornwall did," a source continued.

Markle married producer Trevor Engelson in 2011, but they divorced less than two years later.

Camilla, who used the title Duchess of Cornwall before becoming Queen Consort in the wake of Queen Elizabeth II's death on Sept. 8, was married to British Army officer Andrew Parker Bowles, with whom she has two children, from 1973 to 1995.

She wore a cream-colored dress and coat by Robinson Valentine when she tied the knot with King Charles III in a civil ceremony in 2005, several years after his divorce from Princess Diana and the death of his first wife.

Nicholl's book also covered how the wedding preparation allegedly damaged Prince Harry's relationship with his grandmother.

In the weeks before the royal wedding, a row between Kate Middleton and Markle ensued over whether Princess Charlotte, one of the bridesmaids, should wear tights during the ceremony.

Lady Elizabeth Anson, Queen Elizabeth's late cousin, also told Nicholl that Prince Harry allegedly "shouted" at the Queen's royal dresser Angela Kelly during a row over which royal tiara Markle would be permitted to borrow from the late monarch.

"What Meghan wants, Meghan gets!" Prince Harry allegedly shouted at Kelly, earning him a "stern telling-off" from his grandmother, according to Nicholl.

"The run-up to the wedding was really very difficult for the Queen," Lady Elizabeth claimed to Nicholl. "She was very upset by how Harry had behaved and some of his demands and the way he went about things his own way. I remember her being rather upset by how beastly Harry was being. Their relationship was quite badly damaged by it all."

The Times of London royal correspondent Valentine Low also covered the row about the tiara in his new book, "Courtiers: The Hidden Power Behind the Crown."

The author, who spoke to members of the royal household for his tome, claimed that Prince Harry allegedly tried to pressure the Queen's dresser to "bend the rules" for Markle, who could not try on the tiara when Kelly was not in town.

Prince Harry allegedly used "some fairly fruity language" while talking to Kelly, prompting her to escalate the issue to the Queen, according to the book. The late monarch summoned her grandson to a private meeting after learning about the incident, Low claimed.

"[Harry] was firmly put in his place," Low quoted an unnamed source as saying. "He had been downright rude."

International Business Times could not independently verify the claims of the authors.

Prince Harry and Markle have not publicly addressed the claims.
