"American Horror Story" is continuously bulking up adding season 4 cast member, Finn Wittrock before the "Hotel" opens this fall. Wittrock will be involved in a love triangle with Lady Gaga and Matt Bomer who also became series regulars in the new season. "Hotel" will be AHS's first season without Jessica Lange but reports claim the actress is still set to guest star in it.

Finn Wittrock is the latest cast to check into "American Horror Story: Hotel" as announced by Ryan Murphy himself via his Twitter account, reports TVLine. Wittrock's performance in "Freak Show" is considered to be one of the best, which could lead to his attachment to the fifth season.

The 30-year-old actor and screenwriter played Dandy Mott on series 4, an aspiring performer for Elsa Mars' freak show. Unfortunately, he was not able to join the group so his mother hired a twisted clown instead to keep him amused. Later on, he becomes the main killer.

In "American Horror Story: Hotel," Wittrock will be involved in a love triangle with Lady Gaga and Matt Bomer. Fans speculate that the two characters reportedly play lovers who stay in the hotel while hiding their secrets. As to how Wittrock's character will connect to that story is still under wraps though, it will definitely be as exciting as his "Freak Show" character.

Meanwhile, the former gem of the show, Jessica Lange, recently told The Wrap that she would agree to make a return on the show as the actress enjoys the 4-year collaboration she had with Ryan Murphy.

"If Ryan came to me and said, 'Would you want to do a small character for a couple episodes?' I would absolutely say yes," Lange said. "This was a great collaboration, so I would love to keep working with him."

Whether or not  Jessica Lange is making a comeback on FX's hit series, "American Horror Story: Hotel" will surely level with the success of the previous seasons. Finn Wittrock just got enlisted again to join Lady Gaga and Matt Bomer in a love triangle, following his fantastic performance last season.

"American Horror Story: Hotel" premieres on FX this fall.
