The cast of "American Horror Story" Season 3 just keeps getting bigger: Alexandra Breckinridge is officially on board for "American Horror Story: Coven."

Series creator Ryan Murphy tweeted the news that the "True Blood" actress -- who appeared in Season 1 of "American Horror Story" as young Moira -- will be back for more.

"American Horror Story" Season 3 will center on witches and to take place (at least partially) in New Orleans, as its title implies, and Breckinridge joins an ever-growing cast that includes Jessica Lange, Kathy Bates, Emma Roberts, Taissa Farmiga, Gabourey Sidibe, Evan Peters, Sarah Paulson, Frances Conroy, Lily Rabe, Denis O'Hare, Angela Bassett, Patti LuPone, Grey Damon and Jamie Brewer.

Murphy and the cast have stayed quiet on the details of "Coven," but Peters hinted that viewers won't be let down.

"I'm excited. I think it's gonna be really scary -- much scarier than last season -- and it's gonna be fun. It's going to be really fun to shoot. I'm recharged and ready to go this round," Peters told Golden Derby during a Google Hangout interview.

"American Horror Story: Coven" premieres in October 2013 on FX.
