More exciting casting news out of “American Horror Story: Freak Show.” Creator Ryan Murphy tweeted the above photo, letting fans know that Jyoti Amge, the world’s smallest woman, has joined the cast for the upcoming fourth season.

Amge, 21, is listed in the Guinness Book of World Records as measuring 2 ft 0.6 in tall, which is caused by the condition achondroplasia, or a bone-growth disorder that is one of the most common kinds of dwarfism.

The FX anthology horror show is taking Season 4 to the world of a 1950s Florida “freak show,” with characters like the two-headed woman, the strongman, the bearded lady and Twisty, the killer clown. So … get ready for those nightmares.

“AHS: Freak Show” premieres fall 2014 on FX.
