Journalist and Princess Diana’s former biographer Tina Brown has given a scathing assessment of Meghan Markle, saying she’s “flawless about getting it all wrong.”

Appearing on the latest episode of “The Ankler” podcast, Brown, who served as the editor-in-chief of Vanity Fair from 1986 to 1992, didn’t hold back sharing her opinion on the Duke and Duchess of Sus𝓈ℯ𝓍.

While promoting her new Substack, “Fresh Hell,” the former editor of the New Yorker said that the “Suits” alum, 43, has “the worst judgment of anyone in the entire world.”

Elsewhere, Brown touched on her thoughts about Prince Harry.

“In England, they’re going to constantly make a career out of trashing Harry,” she said. “But actually, the thing about Harry is he’s very good at being Prince Harry.”

“And that’s the tragedy of all of this, is that he is the most talented member of the royal family, without doubt, in terms of being a prince, which is all he does know how to do … he’s really sort of flawless at it.”

As for Markle, she added, “I think he’s pretty much in the thrall of Meghan. The trouble with Meghan is that she has the worst judgment of anyone in the entire world. She’s flawless about getting it all wrong. She really is.”

“She’s a perfectionist about getting it all wrong. Her issue is that she doesn’t listen. She has all these people, asks them their opinion, and then doesn’t follow it. She does what she wants to do,” she said, adding that “all of her ideas are total crap, unfortunately.”

Calling the duke “naïve,” Brown said the exiled royal is “really unschooled in the ways of the world.”

“Being Prince Harry means that I doubt if he ever booked a table in a restaurant. The army was great for him, and he was extremely good and competent in there,” she said. “That really helped turn him into a real person.”

The journalist, who has also worked as the former chief of Tatler, said Harry is “the lamb to the slaughter in this situation.”

“He was terribly impressed by Meghan. He thought that she knew all, she persuaded him that she was the savvy Hollywood wheeler-dealer who could come in and make them stars and all the rest of it. And he just sort of blindly followed her like a child, really,” she added.

The Sus𝓈ℯ𝓍es tied the knot in 2018, and quit the royal family just two years later — a decision that was followed by their trans-Atlantic move.

“Unfortunately, [Markle] made every mistake in the book, and she’s kind of run out of road,” Brown continued.

“I don’t know where Meghan goes. Harry could still, as I say, make a comeback. He’ll always be Prince Harry. He’ll always be the grandson of the Queen and the son of Diana.”

The Post has reached out to reps for the Sus𝓈ℯ𝓍es for comment.

Brown is no stranger to speaking about the royals. In 2022, she released “The Palace Papers: Inside the House of Windsor, the Truth and the Turmoil.”

And in 2007, her Princess Diana biography titled “The Diana Chronicles” became a New York Times best seller.
