Everything we know about the new season of 'American Horror Story' starring Kim Kardashian and Emma Roberts

• The first full trailer for "American Horror Story: Delicate" was released Wednesday.

• In the clip, Emma Roberts' character tries to become pregnant, with seemingly disastrous results.

• Ahead of the new season's premiere, here's everything we know about "AHS: Delicate."

Fans of "American Horror Story" won't have to wait much longer for a new installment of the popular horror anthology series — "AHS: Delicate" is set to premiere in mid-September.

And while Ryan Murphy stalwarts Emma Roberts, Billie Lourd, and Denis O'Hare are confirmed to appear in the new season, there are some surprising newcomers to the series — including Kim Kardashian — this season as well.

Here's everything we know about "AHS: Delicate."

What is the new season of 'American Horror Story' about?

In a series first, "AHS: Delicate" is based (at least in part) on a novel: "Delicate Condition" by Danielle Valentine.

Per her website, Valentine writes "scary books for tweens, teens, and adults." "Delicate Condition," released in August 2023, is her latest book. But according to Valentine's site, she's also written an anthology called the "Merciless" series, which the site describes as "'Mean Girls' meets 'The Exorcist,'" and the 2022 novel "How to Survive Your Murder."

Valentine's site offers a plot synopsis of "Delicate Condition" which reads in part: "Anna Alcott is desperate to have a family. But she's starting to suspect that someone is going to great lengths to make sure that never happens. Crucial medicines are lost. Appointments get swapped without her knowledge. And not even her husband is willing to believe that someone is playing twisted games with her."

In a cover blurb for the thriller, " writer Andrea Bartz described it as "the feminist update to 'Rosemary's Baby' we all needed.'" Valentine, for her part, told Entertainment Weekly she was flattered by that comparison but was more inspired by the 1979 sci-fi horror movie "Alien."

"It is essentially a horror novel about pregnancy," Valentine told Entertainment Weekly. "It's a novel exploring not just the actual physical gruesomeness of what pregnancy is, but also the medical gaslighting that even modern, very privileged women experience as they're going through their pregnancies and the symptoms that I feel we as a culture still don't talk about for strange reasons."

The trailer for "AHS: Delicate" seems as though it will largely follow Valentine's novel. Emma Roberts plays Anna, an actor trying to have both a successful career and a child. And the trailer definitely gives off "Rosemary's Baby" vibes, showing Anna trying desperately to protect herself and her unborn baby from increasingly disturbing threats.

In another first for "American Horror Story," season 12 will be showrun and entirely written by one person: actor and playwright Halley Feiffer. Feiffer previously wrote for another Murphy show "Impeachment: American Crime Story," among other TV series.

In an April statement to The Hollywood Reporter unveiling details of the new season, Murphy described "Delicate" as "ambitious and unlike anything we have ever done."

Who's in the cast of 'AHS: Delicate'?

Kardashian is featured heavily in the trailer. She plays a character named Siobhan Walsh, who appears to be Anna's friend. According to Entertainment Weekly, Siobhan is another actress who's far more successful than Anna. However, the trailer suggests that Kardashian's character doesn't appear to have Anna's best interests at heart.

Murphy told The Hollywood Reporter in April that Feiffer had "written a fun, stylish and ultimately terrifying role" especially for Kardashian.

Another Murphy newcomer appearing in this season is Cara Delevingne, who can be seen in the trailer as both a mysterious woman who follows Anna, and as a nurse doing an ultrasound scan on Anna. It's not clear if this is meant to be the same character, or if Delevingne is playing dual roles. It wouldn't be the first time that an "AHS" actor has played multiple parts in the same season — like Sarah Paulson and Evan Peters in "American Horror Story: Apocalypse." On IMDB, Delevingne is credited as "Meg."

Frequent "AHS" star Denis O'Hare can also seen in the trailer, playing a fertility doctor who's working with Anna to help get her pregnant. Billie Lourd is also back for her sixth season of the show, although there's no word about who's playing yet. Lourd will be joined by her fellow "Apocalypse" and "1984" star Leslie Grossman, who also has an unknown role.

Zachary Quinto, another Ryan Murphy favorite, also confirmed to People that he's got a cameo role in "AHS: Delicate," noting that he met Kardashian while filming it.

"I did a cameo on this season of 'American Horror Story' and I got to meet her," Quinto told People. "She was so lovely and warm and, really, I don't think she needs my advice. She seemed really in her element, and I was really impressed by her spirit and her openness."

He added: "I really look forward to seeing this season because I think she's gonna do a wonderful job."

The upcoming season also stars Matt Czuchry as Anna's husband Dexter Harding, and Annabelle Dexter-Jones, Odessa A'zion, and "Pose" star Michaela Jaé Rodriguez in other roles.

When will 'AHS: Delicate' premiere?

FX confirmed that "AHS: Delicate" will be split into two parts. This isn't the first time the series has divided its season. The tenth season, "American Horror Story: Double Feature," had two entirely separate stories: "Red Tide" and "Death Valley."

"AHS: Delicate" part one will premiere on September 20. The network hasn't confirmed when audiences will be able to watch part two, although the show has controversially remained in production through the writers and SAG-AFTRA strikes. So hopefully, fans won't have too long to wait after part one ends.

"AHS: Delicate" premieres on FX at 10 p.m. ET on September 20, and it'll be available to stream on Hulu the next day.
