She said director John J.

“And John is like, ‘Okay, ladies, that’s enough.

Let’s get back to work.’

And she then looks at me and she goes, ‘Don’t you meanlady?’

and she turns around.”

“I’m trying to process what the f— she just said.

I’m standing there and she walked away.

My blood is boiling.

I didn’t speak to that bitch the entire time after that.

We had scenes together and I never spoke to her.”

Ross added that Roberts eventually commented on the shift in mood.

“She could feel the energy coming off of me,” Ross said.

“She was like, ‘Are you okay?

You haven’t been talking.’

I’m like, ‘Mhm.’

Ross addressed how fans should respond and named the actress in afollow-up poston X, formerly known as Twitter.

“Joke about her being held accountable.

Now THAT’s funny.”

“We’re all sitting around & I’m copying Cody’s accent,” she wrote.

“Emma then copies my voice & laugh and drops it several octaves.

She read me for blood with my own words.

Of course I was self-conscious about my voice on set after that.”

Representatives for Roberts and FX’sAmerican Horror Storydid not immediately respond to EW’s request for comment.

She also claimed thatshe lost out on a potential Marvel opportunityas a result of it.

“It’s not JUST that the idea changed,” she wrote.

“Things change all the time.

I had been auditioning for THREE YEARS for Marvel.

It’s that I was HELD in first position the whole time.”

“just ask somebody about me,” she wrote.

And I’m not even done pulling out the receipts.”

We on strike so you know I got time this week."

Ross appeared in the ninth and 10th seasons ofAmerican Horror Story.
