The actress will appear as Shelly the Nymphomaniac in the new season of "American Horror Story: Asylum" this fall.

Chloe Sevigny hit the packed HBO Post Emmy party wearing a shockingly short black bubble dress that showed off her amazing legs. "It's Miu-Miu!," she shared with us as she sprinted by on her way to Jane Fonda's table.

That was not a surprise since Sevigny is the new ambassador for Miuccia Prada's quirky younger line and appears in the Fall/Winter ad campaign. You can watch her behind-the-scenes video below.

Sevigny, who starred in the highly acclaimed British TV series Hit and Miss, playing a transgender woman, had roles in an episode of Louie, created by and starring Louie C.K., who won an Emmy last night. Sevigny is joining the cast of Portlandia for the hipster comedy’s third season. The Big Love star will play Alexandra, a Portland girl who moves in with Fred Armisen and Carrie Brownstein’s characters

And she will also appear as a character delicioiusly named Shelly the Nymphomaniac in the second season of one our favorite shows, Ryan Murphy's American Horror Story: Asylum. No one seems to last very long on that show, the first season, anyway. We hope her character has staying power, as in staying alive.

We hear there will be a sado-masochist nurse, demon possessions, the inevitable exorcisms, and aliens in the upcoming set in an asylum for the insane. Can't wait.
