Meghan Markle seemed to throw some shade at Kate Middleton after she declined to grace the cover of Vogue.

The Duchess of Sussex guest edited the September issue of Vogue. According to the magazine editor-in-chief Edward Enninful, Prince Harry’s wife declined to appear on the cover because it was “boastful.”

“From the very beginning, we talked about the cover - whether she would be on it or not. In the end, she felt that it would be in some ways a ‘boastful’ thing to do for this particular project,” Enninful said before adding that Markle wanted to focus on the women she admires.

However, Dan Wootton, executive editor of The Sun, reacted to Markle’s reasoning because just three years ago the Duchess of Cambridge agreed to appear on the cover of the magazine.

“The magazine says she [Markle] believes appearing on the cover herself would be ‘boastful’, despite the fact that’s exactly what Kate Middleton did just three years ago,” Wootton wrote.

Middleton graced to do the cover of Vogue in June 2016, but unlike Middleton she didn’t guest edit it. The Duchess of Cambridge’s appearance on the magazine cover was to mark the National Portrait Gallery’s Vogue exhibition for its centenary edition.

For the shoot, Middleton wore a striking green fedora hat, crisp white shirt and brown leather jacket. Prince William’s wife also appeared in a 10-page spread. It was the first magazine shoot that the Duchess of Cambridge ever consented to.

Former Vogue editor-in-chief Alexandra Shulman revealed her excitement in working with Middleton for the centenary issue. According to her, she was very happy to work with the royal.

“For me personally it has been a wonderful experience to have had the opportunity to work with her on this, and I am immensely proud of what we have produced,” Shulman said about working with Middleton.

Aside from Middleton, Princess Diana also graced the cover of Vogue four times. The late Princess of Wales appeared in 1981, 1991, 1994, and 1997.

Markle had already been warned ahead of her editorial gig. According to E! chief news correspondent Melanie Bromley, Markle should be careful not to use her position to influence people on things that are going to be alienating. She also reminded her to stray away from politics. However, some still find Markle’s editorial political.
