"American Horror Story" season 4 cast Sarah Paulson was terrified of the snakes while filming a sex scene in "Coven", as she revealed the tough things she did for creator Ryan Murphy.

"Late Night" show host Seth Myers talked to "American Horror Story" season 4 cast Sarah Paulson who called the "Coven" scene one of the most difficult things she had to do for Ryan Murphy.

Before shooting that scene, the "Glee" creator asked her what she felt, to which she replied: "Um, I don't feel good about it."

However, like a professional that she is, she went ahead with the scene but admitted that, "I did have some tequila because I was a little nervous."

But she said that wasn't the most unnerving thing that "American Horror Story" cast Sarah Paulson did for Ryan Murphy.

"I did have to breastfeed my 35-year-old friend Zachary Qunito," she said, referring to the "Asylum" story arc between Lana Wintes and Dr. Thredson, adding that it was "awkward" talking to her dad after he watched the scene.

For the "American Horror Story: Freak Show," Sarah Paulson has this to say: "Get ready."

"American Horror Story" season 4 cast Sarah Paulson also said that the most difficult part in "Coven" was to wear a prosthetics over her eyes after it was gouged out.

"The hardest part was that it prohibited me from making real eye contact with my fellow actors. So, every time I had to do an intense scene or an emotional scene, or an intimate scene, I couldn't see into anyone's eyes and it just made me realize how much I use that in my work, the other actor's face and reactions," she told TheWrap.

In "Freak Show," "American Horror Story" season 4 cast Sarah Paulson will play a two-headed freak named Bette and Dot.
