Matt Bomer is coming to the "Freak Show." Ryan Murphy, creator of "American Horror Story," announced that the "White Collar" star would be joining the show for one episode. Specific details are being kept under wraps but Murphy told Entertainment Weekly that Bomer's character would be "warped."

FX also released a creepy new teaser that features a man with two tongues or a tongue split in half licking a lollipop. Season 4 of "American Horror Story" premieres Wednesday, Oct. 8 and is set at a circus.

The plot will center around the last remaining freak show in America. An official description reads: "'Freak Show' begins its tale in the quiet, sleepy hamlet of Jupiter, Fla. The year is 1952. A troupe of curiosities has just arrived to town, coinciding with the strange emergence of a dark entity that savagely threatens the lives of townsfolk and freaks alike. This is the story of the performers and their desperate journey of survival amidst the dying world of the American carny experience."

Bomer joins another freak show newbie, Jyoiti Amge aka the smallest woman in the world. According to the Guinness Book of Records and the Limca Book of Records, the 20-year-old stands a little over 2-feet-tall. Details about her character have not been released.
