Angelica Rossclaims she has received an apology fromEmma Robertsfor her behavior on the set ofAmerican Horror Story: 1984.

One day after thePosealum, 42, accused her former costar, 32, of making a transphobic comment on set of the FX series, Ross shared onX(formerly known as Twitter) that Roberts reached out to make amends.

“Thank you @RobertsEmma for calling and apologizing, recognizing your behavior was not that of an ally,” she shared on Wednesday. “I will leave the line open to follow up on your desire to do better and support social justice causes with your platform.”

Representatives for Roberts, Ross and FX have not returned PEOPLE’s multiple requests for comment.

“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 goes, ‘John, Angelica’s being mean,'” she claimed, seemingly referring toAHSdirector John J. Gray.

Ross claimed that Gray then said, “Okay, ladies, you know, that’s enough. Let’s get back to work.”

The actress continued, “[Roberts] then looks at me, and she goes, ‘Don’t you mean lady?’ And she turns around like this and covers her mouth. I’m staring at her, looking her dead ass in the [camera], and I’m like, trying to process the f— she just said.”

Ross said that she feared retaliation if she reported the alleged incident, claiming, “My blood is boiling because I’m like, if I say something, it’s gonna be me that’s the problem. I know this because there was someone who spoke up about what she was doing, and they got repercussions from it.” (PEOPLE has reached out to Roberts’ rep regarding this claim.)

TheTransparentalum admitted that she no longer spoke to Roberts after the alleged on-set encounter.

“When I saw that happening, I was just like, ‘I’m done. I’m done.’ I didn’t speak to that b—- the entire time after that,” she claimed. “She said to me she could feel the energy coming off of me.”

She continued, “She was like, ‘Are you okay? You haven’t been talking.’ I’m like, ‘Mmhmm,’ 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.'”

Ina separate tweeton Wednesday, Ross alleged another troubling incident with Roberts and what seems to be their1984costar Cody Fern.

“We’re all sitting around & I’m copying Cody’s accent. Didn’t know he had one. Emma then copies my voice & laugh and drops it several octaves,” she wrote. “I was SHOOK. She read me for blood with my own words. of course I was self conscious about my voice on set after that.”

Also on Monday, Ross accusedAHScreatorRyan Murphyof ghosting her after proposing they work together on an all-Black season of the FX series.
