Lily Rabe Returning To 'The Good Wife' And More Casting News

Lily Rabe is returning to "The Good Wife."

The "American Horror Story" star is reprising the role of Petra Moritz, a character she originated in Season 2. In the episode, "Going for the Gold," the Justice Department refuses to reveal who will be testifying against Eli Gold (Alan Cumming), so Elsbeth Tascioni (Carrie Preston) takes Assistant US Attorney Josh Perrotti (Kyle MacLachlan) to civil court for defamation in order to force him to answer her questions under oath.

"Law & Order" veteran S. Epatha Merkerson will also appear as a judge. Other guest stars in the episode include Amanda Peet, Maura Tierney, T.R. Knight and Dominic Chianese.

Rabe will also return to "American Horror Story" for Season 3.
