Emma Roberts is facing accusations by co-star Angelica Ross.

The 32-year-old and the 42-year-old actresses worked together on 2019′s American Horror Story: 1984, and on Tuesday (September 19), Angelica spoke out on an Instagram Live about the experience.

Angelica explained that her relationship with a co-star became bad when a playful moment led to an alleged transphobic remark.

She also accused her co-star of playing “mind games” with everyone on set.

While Angelica did not explicitly say the full name “Emma Roberts,” she said “The person I am talking about is definitely Miss E.R.,” via TVLine.

“I’m standing in front of Emma, talking to her like this, and she’s in front of me, her back against the mirror,” she said. “She goes, ‘John, Angelica‘s being mean.’”

The “John” in question was not specified, though two episodes of the season they both starred in were directed by John J. Gray, via Newsweek.

“I know she’s not being for real,” she continued.

“She’s just being whatever. And John is like, ‘OK, ladies, that’s enough. Let’s get back to work.’ And she then looks at me and she goes, ‘Don’t you mean lady?’ And she turns around like this and covers her mouth [with her shirt].”

Once Emma turned away, Angelica said she couldn’t “see I’m looking at her dead a** in the camera, like, ‘What the f*** did you just say?’ And I’m standing there looking her dead a** in the damn thing, and I’m like, trying to process [what] the f*** she just said.

“I’m standing there, she walked away, my blood is boiling. Because I’m like, if I say something, it’s gonna be me that’s the problem. And I know this because there was someone who spoke up about what she was doing and they got repercussions from it. Not her—they did,” Angelica continued.

“So when I saw that happening, I was just like, ‘I’m done.’ I didn’t speak to that b**** the entire time after that. So we had scenes together and I never spoke to her. She said to me she could feel the energy coming off of me. She was like, ‘Are you OK? You haven’t been talking.’ I’m like, ‘Mmmhmm.’ ‘Cause b**** don’t play me. You’ve been playing mind games with everybody on the set and everybody’s been waiting for the moment that you would get me.”

Angelica Ross also said that Ryan Murphy accepted her pitch of doing a season of American Horror Story starring four Black women, but then ghosted her and never responded to follow-ups about the project.
