Matt Bomer will guest star in the upcoming fourth season of FX's horror anthology series "American Horror Story."

Speaking at Entertainment Weekly's Emmy Party, series co-creator Ryan Murphy revealed that the 36-year-old actor will appear on one episode of "American Horror Story: Freak Show."

Murphy is excited to reunite once again with the "amazing" actor, who he has worked with in his 2014 drama television film, "The Normal Heart," Entertainment Weekly reported. The critically acclaimed HBO TV movie received 11 Emmy nominations with Bomer earning a nod for Outstanding Supporting Actor in a Movie for his performance as Felix Turner.

Aside from "The Normal Heart," the "White Collar" actor also appeared on Fox's musical dramedy "Glee" as Blaine's (Darren Criss) older brother, The Hollywood Reporter noted. "Glee," which is set to return on Fox for its sixth and last season next year, is also co-created by Murphy.

"I try to get him to do everything for me," Murphy told Entertainment Weekly. "I sent him a text that said, 'First right of refusal, here's the role.' It's very...warped."

Murphy added that he had to work around the schedule of the actor, who will be reprising his stripper role as Ken in "Magic Mike XXL," in order to have him appear on "American Horror Story: Freak Show."

Details about Bomer's character are being kept under wraps. FX and parent company Fox has not confirmed the news, E! News reported.

Bomer joins the show's returning cast members including Jessica Lange, Kathy Bates, Angela Bassett, Frances Conroy, Sarah Paulson, Emma Roberts, Gabourey Sidibe and Evan Peters.

The Season 4 of the show will also star newcomers Michael Chiklis ("The Shield"), Finn Wittrock ("All My Children"), Wes Bentley ("The Hunger Games"), John Carroll Lynch ("Fargo"), Patti LaBelle ("Miami Vice") and the world's smallest woman, Jyoti Amge.

"American Horror Story: Freak Show" premieres on FX on Wednesday, Oct. 8.
