As "American Horror Story: Freak Show" premieres on FX, spoilers regarding season 4 have surfaced.

First, spoilers confirm that "American Horror Story" season 4 episode 4 will go into the backstory of Twisty the Clown.

"There's a big story that explain why he's doing what he's doing," said co-creator Ryan Murphy, adding that the episode is "somewhat based on an urban myth."

Meanwhile, spoilers confirm that the two-part Halloween episode will revolve around Wes Bentley's character, Edward Mordrake. According to TVLine, this character is based on a supposed real-life figure born with a face on the back of his head.

"That's also the episode where Jessica [Lange] sings Lana Del Rey," added Murphy, "which is quite something to behold."

Speaking of something to behold, spoilers also confirm that the opening title sequence for "American Horror Story: Freak Show" has plenty of clues as to what's coming this season, including the "intersex" character with one leg between its legs.

But before that, fans can expect more conflict between Emma Roberts and Sarah Paulson's characters. Reportedly, when Roberts becomes a love interest for Jimmy (Evan Peters), Dot "has it out for [her] right away."

In addition, "White Collar" star Matt Bomer is also said to make an appearance in "American Horrror Story: Freak Show" season 4 in the fifth episode of the series, which will include an encounter with Michael Chiklis' character which Murphy describes as "a true horror scene."

Apparently, Bomer said the whole experience had a "demented Tennessee Williams" feel.
