The Big C co-star Gabourey Sidibe is joining the cast of American Horror Story: Coven. Ryan Murphy announced the casting on Twitter this morning. In his typical fashion, he didn’t disclose any details about the character Sidibe will be playing. The Oscar-nominated actress joins another heralded new AHS addition, Oscar winner Kathy Bates, in addition to returning cast members Jessica Lange, Sarah Paulson and Taissa Farmiga. The final installment of The Big C premieres tonight.

Newcomer Alex Saxon has landed a recurring role on the new ABC Family series The Fosters, produced by Jennifer Lopez’ Nuyorican Productions. Saxon, repped by Sager Entertainment and Greene & Associates, plays Wyatt, an intriguing outsider who Callie (Maia Mitchell) recognizes as one of her own kind. His credits also include the CBS drama pilot The Advocates and Showtime’s upcoming series Ray Donovan.
