Meghan Markle did something to Kate Middleton's staff that did not please the latter.

According to Abbie Llewelyn, a journalist for Express, the Duchess of Cambridge "scolded" the Duchess of Sussex due to her treatment of the former's staff. Middleton reportedly told Markle that she should not berate her staff as they were under her care.

“Her and Kate fell out when she [explicit] Kate's staff,” a source told The Sun.

“That's unacceptable, they're my staff and I speak to them,” Middleton told Markle.

“It's a tricky situation but it was a one-off and they are determined to maintain a positive relationship even though they are obviously very different in their approach,” the source added.

Middleton and Markle's alleged feud has been making rounds online. According to an insider, the two duchesses are very different and they don't really get along.

Their beef was reportedly the reason the Duke and Duchess of Sussex decided to leave Kensington Palace. The palace already confirmed that Prince Harry and Markle will move to Frogmore Cottage in Windsor because it is more spacious.

However, prior to that, the couple was initially set to move to a bigger apartment in Kensington Palace that was occupied by the Duke and Duchess of Gloucester. The latter was asked to vacate the place to make way for the younger royals.

“The initial plan was for Harry and Meghan to move out of their cottage in the grounds of Kensington Palace and into one of the main apartments,” a royal source told Emily Andrews, a royal correspondent for The Sun.

“But there has been a bit of tension between the brothers. Now Harry and Meghan don't want to live next to William and Kate and want to strike out on their own. They need more room and hope Frogmore Cottage will be ready in time for when they have the baby.”

Prince Harry and Markle's decision to leave the palace grounds only intensified their rumored rift with the Duke and Duchess of Cambridge. In fact, many find it odd why they decided to move to Windsor.

"It does seem odd especially as TRH The Duke & Duchess of Gloucester vacated their Kensington Palace apartment 1, after living there for 46 years so Harry & Meghan could move in!!" one user wrote on Twitter.
