Meghan Markle would one day have to curtsy to Kate Middleton when the latter becomes queen.

Paul Burrell, Princess Diana’s former butler, said in the documentary “Kate V Meghan: Princesses At War?” that the Duchess of Sussex should understand that it is a protocol for her and the other royals to curtsy to Queen Kate.

In the one-off documentary, the Fab Four’s relationship was also discussed. It was revealed that Prince William, Middleton, Prince Harry and Markle were once dubbed as the future of the monarchy. However, this may no longer be the case.

Katie Nicholl, a royal author, praised Markle for doing a wonderful job during the first six months of being a royal. But the expert also noted that all of a sudden, the Duchess of Sussex’s flaws were uncovered by the media, and this changed everything for her.

It was previously claimed that Markle made Middleton cry during Princess Charlotte’s bridesmaids fitting ahead of Prince Harry and Markle’s May 19 nuptials. There were also speculations suggesting that the former actress’ staff resigned due to her difficult personality.

Ahead of her wedding at St. George’s Chapel in Windsor Castle, Markle was also rumored to have requested to wear a tiara from the Royal collection but was denied by Queen Elizabeth II.

Multiple publications have also claimed that Markle and Middleton have been at odds with each other as early as February 2018. However, a palace source said that there is no truth to the rumors.

Nicholl is also convinced that Markle and Middleton are not the ones feuding with each other. Rather, Prince William and Prince Harry are the ones who haven’t been getting along well.

“It goes back to Harry’s choice of Meghan. William and Harry are a brilliant team, but they were also fiercely competitive,” Nicholl said in the documentary “Kate Middleton: Working Class to Windsor.”

Rumors about the royal siblings’ feud once again heightened after they seemingly ignored each other during their Christmas Day church service at the Sandringham estate with Her Majesty and the royal family. Prince William and Prince Harry stood close to each other, but they never talked.
