Angelica Ross says Emma Roberts called her amid transphobia backlash to apologize for misgendering her on the 'AHS' set

• Angelica Ross thanked Emma Roberts for apologizing amid the backlash against the "American Horror Story" star.
• The controversy began after Ross said Roberts once made a transphobic remark about her on set.

"Pose" star Angelica Ross revealed on X (the platform formerly known as Twitter) that her "American Horror Story" costar Emma Roberts called to apologize amid controversy that ignited after Ross said Roberts made a transphobic remark about her on set.

"Thank you @RobertsEmma for calling and apologizing, recognizing your behavior was not that of an ally," Ross wrote, adding: "I will leave the line open to follow up on your desire to do better and support social justice causes with your platform."

Ross' post comes after the "Pose" star spoke about her experience working on "American Horror Story: 1984" with Roberts.

According to Variety's Zach Scharf, Ross said during a recent Instagram live that while joking around in between takes on the set of "AHS: 1984," "Emma" (Ross appeared to be referring to Roberts, although she didn't say her full name) misgendered Ross, a trans woman.

Ross reportedly recalled in the Live that she and (presumably) Roberts were jokingly reprimanded by "John" (who, as Variety notes, would appear to be one of the show's directors, John J. Gray) after Roberts said that Ross was being "mean."

Gray, Ross recalled, said to them: "OK ladies, you know, that's enough. Let's get back to work."

According to Variety, Ross recalled that Roberts then turned to her and said: "Don't you mean lady?"

Ross said she was outraged by Roberts's comment, which seemingly suggested that Ross wasn't a woman.

"I'm standing there, she walked away, my blood is boiling. Boiling because I'm like, if I say something, it's gonna be me that's the problem," the "Claws" star said.

Roberts subsequently trended on social media after Ross shared the story, with many calling her out for transphobia.

Representatives for Roberts and FX (the network that airs "American Horror Story") didn't immediately respond to Insider's requests for comment. A representative for Ross declined to comment.
