The 46-year-old actress has appeared in nine of the last 10 seasons of Ryan Murphy's much-loved show - and can currently be seen playing a homeless woman called Tuberculosis Karen in "AHS: Double Feature".
Asked about her next Murphy collaboration during an appearance on "Watch What Happens Live", Sarah replied, "I don't know. It's the first time in about three years where I don't know."
"I think this is my last season of Horror Story, probably," she sighed. "I mean, I don't know. Every time (Murphy) comes to me with some whack-a-doodle character, I tend to be like, 'Yes, let's do it!' I don't know, this is the first time. So we'll see."
Following "AHS: Double Feature", there are two more confirmed seasons of "American Horror Story".
Sarah Paulson previously said she felt "trapped" by her role in "AHS: Roanoke".
The actress who appeared in all seasons of the show admitted, "As much as it's my home and I've loved it always, it was the first time I felt like I wish I could have gone to Ryan and said, 'Please let me sit this one out.' You know, 'Let me out.' "
She added, "I was happy to be back for Cult but Roanoke, I kinda went kicking and screaming."
She wasn't feeling inspired because she took on the role immediately after playing Marcia Clark in 2016 drama "The People v. O.J. Simpson".
