Naomi Campbell and Lily Rabe are the two newest additions to the cast of "American Horror Story" season 5 which airs on FX in October.

TV Line reveals that the supermodel will go toe-to-toe with Lady Gaga as "a fashion editor who pays the ultimate price for her critiques." Campbell is expected to appear in a multi-episode arc. Aside from her encounter with the diva, she is also slated to act alongside AHS alum Angela Bassett. 

Meanwhile, another former cast member of FX's anthology series, Lily Rabe, will make a comeback. Entertainment Weekly reports that in "Hotel," she will portray the character of a famous serial killer. The actress has appeared in all four seasons of AHS, and in a cameo role in the "Freak Show," where she played as an evil nun.

In the latest installment of AHS, Breathecast predicts that Rabe will be an evil ghost who roams the titular hotel. The showrunners have yet to reveal details about her character, though, so everything is just speculations. 

Ryan Murphy, the show's co-creator, shared some tidbits regarding the new installment during the Comic-Con panel. Aside from being "the darkest and spookiest" of all seasons, "Hotel" would feature most of the characters succumbing to the evil inside them. According to him, Evan Peters, Kathy Bates, and Matt Bommer, to name a few, will be the "bad boys and girls" of season 5.

Meanwhile, Variety reports that Lady Gaga's character will be involved in fashion and that her part is specifically written for her.

"When you work with someone like her, you sign up for something that is larger than life, and I think that's what you want. Part of her role involves fashion. You want Lady Gaga to look a certain way. The designers have been coming out of the woodwork with looks for her," Murphy said.
