Speaking to The Wrap, Sarah also gave an update on filming, explaining she's currently shooting for her role as Linda Tripp in American Crime Story, and revealed how she'll be playing both roles at the same time.
"Well, here's the deal, I haven't started Horror Story. We're only into episodes one and two and about to start three of Crime Story. Though Horror Story is shooting, they haven't been able to have me yet because of what I'm doing on Crime Story," she said.
"But in a minute or two, that will start to be in front of me, of trying to do both of them at the same time. So I don't know yet what it's like to play the gal I'm playing over on Horror Story this year, but I can tell you that I'm looking forward to it.
"But the most exciting thing for me is I get to have a hair colour I've never had on the show, nor have I ever had it in life, and it's something I've always dreamt of doing, never done. So I get to live out that fantasy, so that's exciting for me."
Back in December, we told you how Season 10 of American Horror Story had kicked off filming. Lily Rabe, who has appeared in every season of the show, told Digital Spy at the beginning of the month that they were "starting tomorrow".
The tenth chapter in Ryan Murphy's anthology series was delayed due to the ongoing coronavirus pandemic, however Lily did not reveal the theme for the upcoming season and remained tight lipped on details regarding the new episodes.
"I know there are things that have already been said that I can just say again, but you already know them. And there's nothing new that I can say. But I think it's going to be - I know it's going to be great. I'm really, really excited about it," she said.
Us too, Lily!
