Kim Kardashian is one busy woman. Between her many businesses, her family’s reality show and being a mom of four, it’s hard to believe she can squeeze one more thing into her schedule.

Yet somehow, she managed to put on her acting hat for Ryan Murphy‘s American Horror Story: Delicate.

Despite Kardashian’s hectic lifestyle, her co-star Annabelle Dexter-Jones revealed that she was a “calming presence on set” — even if she herself felt “anxious” for the mogul at times.

The actress stopped by Thursday night’s (April 4) episode of Watch What Happens Live, where she dished to host Andy Cohen and Summer House star Amanda Batula about her time working with Kardashian.

“Filming with Kim K was really — she’s a very calming presence on set,” she said. “Like, very grounded, very focused.”

However, all the “downtime” that comes with filming a TV show made Dexter-Jones feel “anxious” for the Skims founder.

“There’s a lot of downtime with that job so I was a bit anxious for her because there was a lot of dead time,” she said. “I’m like, she could be in court at a hearing or doing another one of her 10 jobs. But it was great.”

In the show, Kardashian plays Siobhan Corbyn — the publicist and best friend of budding actress Anna Victoria Alcott (Emma Roberts). While AHS fans were hesitant to welcome Kardashian aboard the hit franchise, many — including DECIDER’s own Raven Brunner — said that she “impresses in the role.” The reality star only continued to showcase her talents in the premiere of the second part of the season, which aired on April 3, when she slapped Roberts across the face.

“Anytime you try something, you just have to have the intention of growing and challenging yourself,” Kardashian said in a behind-the-scenes teaser ahead of the season premiere. “Then you just kinda release and have fun.”
