Don't mess with the Duchess of Cambridge.

Tatler magazine recently ran a cover, dubbed "Catherine the Great," about Kate Middleton and her royal duties but it seems that not everyone thinks it's so great because after it's release Kensington Palace issued a statement regarding the British publication's contents.

"This story contains a swathe of inaccuracies and false misrepresentations which were not put to Kensington Palace prior to publication," a Palace spokesperson said on Wednesday, according to Entertainment Tonight.

Despite the negative response from the royals, a spokesperson for the magazine revealed, "Tatler's Editor-in-Chief Richard Dennen stands behind the reporting of Anna Pasternak and her sources."

"Kensington Palace knew we were running the 'Catherine the Great' cover months ago and we asked them to work together on it," they added. "The fact they are denying they ever knew is categorically false."

The overarching message throughout the Tatler article was that Kate is a hard worker. However, in the process, the magazine slammed Meghan Markle and Prince Harry.

The "Catherine The Great" feature claimed that the mother of three was "furious about the larger workload" due to the Duke and Duchess of Sussex stepping down as senior members of the royal family on March 31.

"Of course she's smiling and dressing appropriately but she doesn't want this," a source shared in the piece. "She's working as hard as a top CEO, who has to be wheeled out all the time, without the benefits of boundaries and plenty of holidays. She keeps her head down because the prize of being queen is so great. She models herself on the Queen and now speaks like the Queen."

Tatler isn't the first publication to report on Kate's supposed ill-feelings towards her brother-in-law's wife. The two women have been reported to be feuding ever since Meghan stepped on the scene years ago. There was never any hard evidence of the supposed tension between them, but Prince Harry did admit to a slight rift between himself and his brother and Kate's husband Prince William, during the October 2019 documentary "Harry & Meghan: An African Journey."

"Inevitably, you know, stuff happens, but we’re brothers. We’ll always be brothers," the father of one told ITV interviewer Tom Bradby, admitting that they are on "different paths."
