Chloe Sevigny to Play a Nympho on ‘American Horror Story’

'American Horror Story' has added another member to its already somewhat ecletic season two cast. Former 'Big Love' star, Chloe Sevigny is in final talks to join Jessica Lange, Adam Levine, Zachary Quinto, Lily Rabe, Sarah Paulson and Evan Peters on Ryan Murphy's FX thriller.

Sevigny will play "Shelly the Nymphomaniac," reports EW, a role that was crafted with the actress in mind. Shelly is a "mortal enemy" of Jessica Lange's character, who runs an East Coast mental institution where the show's sophomore season will take place.

If you missed out on 'AHS' first season, which saw Dylan McDermott and Connie Britton as the unfortunate buyers of a haunted L.A. mansion, no need to worry. The show's anthology structure means viewers will be introduced to a whole new cast of unwitting victims and their eerie tormentors, from both this world and beyond. Though Lange is staying on, she'll play a character opposite to season one's creepy meddling neighbor, Constance Langdon. Quinto, Rabe, Paulson and Peters are also back, but in entirely new roles.

As for Sevigny, the 'Kids' and 'American Psycho' star is known for her edgy roles. If anyone can go from a polygamous marriage to an insane asylum, it's Chloe Sevigny.
