LOS ANGELES, Oct. 29 (UPI) -- Neil Patrick Harris has joined American Horror Story: Freak Show.
The 41-year-old actor and husband David Burtka will both guest star on late-season episodes of the FX series. Harris will portray "a chameleon salesman," while Burkta will appear in "a sexy storyline" with freak show manager Elsa Mars (Jessica Lange).
"I wrote a letter to Ryan asking if I can be in it," Harris revealed on EW Radio. "I just love those series and Coven was fantastic ... to do one that involves any kind of freak, circus nonsense is going to be so unsettling to watch. Can't wait!"
Freak Show premiered October 8, and takes place in Jupiter, Fla., in 1952. Sarah Paulson co-stars as conjoined twins Bette and Dot Tattler, with Michael Chiklis as strongman Dell Toledo, Kathy Bates as bearded lady Ethel Darling, Evan Peters as Ethel's son Jimmy Darling and John Carroll Lynch as villain Twisty the Clown.
Harris is best known for portraying Barney Stinson on CBS series How I Met Your Mother, and recently starred in Hedwig and the Angry Inch on Broadway. In addition to Freak Show, the actor is slated to host a new variety show on NBC.
American Horror Story: Freak Show airs Wednesdays at 10 p.m. ET on FX.
