"American Horror Story" veteran Zachary Quinto said Kim Kardashian was "in her element" on the set of the show's upcoming season, People first reported.

Quinto, who has starred in three seasons of the show, announced at the Tribeca Film Festival that he's making a cameo on the 12th season of "AHS," a horror anthology created by Ryan Murphy that's been on the air for over a decade.

Kardashian surprised fans in April by announcing she'd been cast in the new season of "AHS" alongside Emma Roberts.

Season 12, titled "Delicate," is partly based on Danielle Valentine's upcoming novel "Delicate Condition," according to The Hollywood Reporter. The book, according to Amazon, is about "a woman convinced a sinister figure is going to great lengths to make sure her pregnancy never happens―while the men in her life refuse to believe a word she says."

According to People Magazine, Quinto gave reporters insight into what it was like working with the reality star at the film festival, taking place in New York City from June 7 to June 18.

"She was so lovely and warm and, really, I don't think she needs my advice," Quinto said. "She seemed really in her element, and I was really impressed by her spirit and her openness."
