The actress also hasn't heard back from series creator Ryan Murphy, who she said "ripped" into her during an angry phone call.

Though Palmer never reveals the identity of the co-star that made the remark, she did share that they have yet to apologize. In an interview with The Cut published Tuesday, Palmer said that even though the co-star has never apologized for what they said, they did reach out to her on Instagram to congratulate Palmer on the release of her book.

"She knows what she did," said Palmer, who revealed her costar had been in touch and reached out when she released her book 'Master of Me' in November
