Michael Chiklis is returning to FX, this time as part of the ensemble on “American Horror Story: Freak Show.”

Chiklis will play the former husband of Kathy Bates’ character and father of Evan Peters’ character in the fourth-season incarnation of “American Horror Story.” Creator Ryan Murphy announced the fan-friendly casting as part of the “AHS” Paleyfest panel on Friday at the Dolby Theater.

Murphy disclosed earlier this week that “Freak Show” would live up to its title. Set in the early 1950s in Jupiter, Fla., “AHS” mainstay Jessica Lange will play a German expatriate who runs a sideshow circus.

Chiklis starred in the edgy cop show “The Shield” that put FX on the map with original programming map from 2002 to 2008. The TV vet most recently starred in CBS’ period drama “Vegas” last season.

Chiklis was on hand for Friday’s Paleyfest session to trumpet the news.
