Over the past few days, we’ve been reporting on the fallout from a Tatler Magazine story about Kate Middleton that made a number of negative claims about her, including that she has become overwhelmed with her workload as a royal in the wake of the departure of Meghan Markle and Prince Harry.

Now, it’s been revealed that Kate feels particularly “hurt and upset” by the article because the magazine’s editor-in-chief is a “close friend” from college who has vacationed with her twice.

The piece, which was written by journalist Anna Pasternak, claims that Kate has felt “exhausted and trapped” since Meghan and Harry stepped down. The story also described Kate as having “an aura of blandness” and that she has developed a “posher” accent after being born a commoner. Kate and her husband Prince William have since taken legal action against Tatler and demanded the story be removed, though the publication has refused to comply with this demand so far.

Sources say Kate is particularly hurt because Richard Dennen, the editor-in-chief of Tatler, is an old friend of hers going back to their days as students at the University of St. Andrews.

“Kate remains hurt and upset by the article. It was very unpleasant,” a source told The Sun. “But she also feels betrayed, as Richard had been a friend from the St. Andrews set. Kate never saw this coming. There are a lot of unanswered questions, particularly who said these things to Tatler because her real friends would never talk that way about her.”

Tatler rubbed salt in the wounds by specifically saying afterwards that Dennen himself stands by both the story and the reporting.

“Editor-in-chief Richard Dennen stands behind the reporting of Pasternak and her sources,” Tatler said in a statement. “Kensington Palace knew we were running the ‘Catherine the Great’ cover months ago and we asked them to work together on it. The fact they are denying they ever knew is categorically false.”

Born in Chicago, Dennen became close to Kate at St. Andrews, where they both took the same art history classes together. They even went to France with one another in 2004 when Kate was on a relationship break with William. The pair was so close that Dennen even once shared a photo he’d taken of Kate eating a sandwich at an airport, captioning it, “Before life got serious and we still ate wheat and flew economy.”

It is also believed that Dennen was a guest at Kate’s 2011 wedding to William.

“She’s very measured, very controlled,” Dennen once said of her. “That is perfect because you don’t want someone who’s going to be falling out on the Kings Road face down, wasted after a boozy session.

“There was this nightclub that everyone went to called Boujis and she was famous for always nipping into the bathroom, checking her hair and make-up before she left because she knew there were photographers waiting outside,” he added.
