He’s on the defensive.

Superproducer Ryan Murphy is blasting critics of his upcoming show “American Love Story,” which is about the ‘90s It couple, John F. Kennedy Jr. and Carolyn Bessette-Kennedy.

“It’s very interesting that people become so inflammatory,” Murphy told Variety in a story published Thursday. 

He was referring to the backlash when he posted a “first look” photo of actors Paul Kelly and Sarah Pidgeon in costume in the roles last week. 

Critics derided the clothing as being “completely off” and looking like “Zara,” and failing to capture the essence of the fashion icons. 

“This is OFFENSIVE,” one indignant fan posted on Twitter, alongside the photo of Pidgeon in costume. 

Another critic blasted it as, “This is so Zara Basic 2015.” 

“Her blonde hair is all wrong,” wrote another person. “She was famous for the varying blonde tones, the highlights and lowlights. It should be warmer. Not platinum. Please try again.”

“Doesn’t capture the essence of CBK,” another person commented. 

“Nope. Accuracy & research in costume design. Even in test photos. I’m underwhelmed. That shade of blonde …You can’t just throw on a modern (cheap) coat and thinks it’s giving this,” they concluded, sharing a photo of the real Bessette-Kennedy. 

Murphy told the outlet that the actors’ outfits were not pieces they’ll wear on the show. Rather, they were thrown together for lighting and color tests – to get ahead of the paparazzi set photos when the production films in New York City. 

“There were comments like, ‘I hate that coat, Carolyn would never have worn that,’” Murphy said.

“That was just a coat we threw on for color. People were writing, ‘How dare you use the No. 35 Birkin bag? She wore a 40!’ Yes, we have a 40 but we just threw on a bag from another costume department because that was the soundstage we were on.”

He said he had a 10-person “style advisory board” to put together Bessette-Kennedy’s look. 

Bessette-Kennedy was famous for her high-end fashion. The socialite died at age 33 in a plane crash off the coast of Martha’s Vineyard in 1999. JFK Jr. died with her in that crash, at age 38. 

Murphy said the production will use some clothing from the real Bessette-Kennedy. 

“We have multiple pairs of Manolo black heels and sandals from 1992 to 1999. We have the Manolo boots she wore in black and brown. We have her Prada tall boots. We have her Prada bags,” he explained. 

“We have the Birkin No. 40 that we have taken to a specialist to scruff it up so it looks identical to the one she would wear half-open on the subway.”

Murphy insisted that the public reaction is “not fair.”

“We’re writing a story about a person – an unknown person – who falls in love with the most famous man in the world and suddenly she can’t leave her house. She was constantly being photographed, being called a c – – t by the paparazzi,” he said. 

Regarding the scrutiny on the first look photos, he said, “They’re doing to our Carolyn, what they did to the real-life Carolyn. It’s not fair.”

This isn’t Murphy’s first time landing in hot water with the real-life subjects of his shows. 

His 2024 show “Monsters: The Lyle and Erik Menendez Story” faced criticism for suggesting an incestuous relationship between the infamous brothers who went to jail for the 1989 murder of their parents, Jose and Kitty Menendez.

Erik, 53, spoke out in a statement and said the “dishonest” show is filled with “horrible and blatant lies” about himself and his brother Lyle, 56.

Some relatives of Jeffrey Dahmer’s victims also spoke out against Murphy’s other Netflix series “Dahmer – Monster: The Jeffrey Dahmer Story.”

On Thursday, former President John F. Kennedy’s grandson Jack Schlossberg put Murphy on blast and said that “American Love Story” is “grotesque.” 

“Lately, my news feed has been filled with pictures of my uncle, John F. Kennedy Jr., a great man,” Schlossberg, 32, said in an Instagram video, referencing the Murphy-produced show.

“For those wondering whether his family was ever consulted, or has anything to do with the new show being made about him, the answer is no. And there’s not much we can do.”

The Kennedy scion added, “For the record, I think admiration for my Uncle John is great. What I don’t think is great is profiting off of it in a grotesque way.”

“American Love Story” premieres on FX in February 2026.
