Another series alum has joined the cast of "American Horror Story: Hotel." According to creator and showrunner Ryan Murphy, long-time "AHS" star Evan Peters will appear in the next inception of the highly rated horror anthology series.

Murphy tweeted: "This season, Evan Peters will be waiting for you in Room 64. #AHSHOTEL." 

The 28-year-old actor portrayed various roles in "American Horror Story" since FX premiered the series back in 2011. He played the sociopath ghost named Tate Langdon in "Murder House"; serial killer Kit Walker in "Asylum"; the resurrected-from-the-dead college student named Kyle Spencer in "Coven"; as well as the Lobster Boy named Jimmy Darling in the recently concluded "Freak Show." 

Peters will join another stellar lineup of actors in the coming "AHS" season, including Sarah Paulson, Matt Bomer, Kathy Bates, Cheyenne Jackson, Wes Bentley, Chloë Sevigny, as well as pop superstar Lady Gaga. Out of all the actors for season 5, Peters and Paulson are the only ones who appeared in all previous four seasons of the horror thriller. 

Meanwhile, Bomer recently teased during the recently concluded CinemaCon in Las Vegas that his character will extensively interact with Lady Gaga in the upcoming "AHS" season.

"I know that I'll be working with Stefani [Lady Gaga], pretty extensively, so I'm excited about that," the actor said. "Our storyline is really, really fun, and I think what they're doing with our characters is really unique and kind of an original take on it." 

However, Bomer did not expound further if his character and Lady Gaga's will be lovers in the series. 

On the other hand, Peters' girlfriend Emma Roberts, who also appeared in several installments of the horror anthology, is still unconfirmed if she will join the "AHS" cast this season. However, she is already included in another Murphy-created comedy-horror show for FOX titled "Scream Queens," alongside "Glee's" Lea Michele.
