'That's unacceptable': Kate Middleton slammed Meghan Markle for berating staff before royal wedding - report

Kate Middleton blasted Meghan Markle in the lead-up to this year's royal wedding after the former Suits star "bollocked" a member of staff, according to a tabloid's royal source.

The Sun reports that the royals "fell out" after Meghan berated one of Kate's aids, which the Duchess of Cambridge did not take lightly.

The UK tabloid's source says Kate confronted Meghan, telling her: "That's unacceptable, they're my staff and I speak to them."

The rumours come after reports of a growing rift between the the two royal couples, bolstered by it being announced that Meghan and Prince Harry reneged on plans to live next-door to Kate and Prince William, opting instead to move to Windsor. 

Last week, multiple media outlets alleged that Kate had been "left in tears" by Meghan during a "stressful" dress fitting for her daughter Princess Charlotte before the wedding.

Kensington Palace denied claims that the row ever happened, despite not usually commenting on speculation from the press.

Kate also appears to be attempting to dispel rumors of any drama between the Duchesses, telling fans last week that she was "absolutely" excited for Meghan and Harry's new baby.
