The 65-year-old actress had nothing but good words when she spoke of her experience working with her co-actors and staff on four seasons in FX's "American Horror Story." 

"In all the madness, I've loved the writers, my actors, Ryan [Murphy] and the whole, I mean, insanity of it," shared Lange. 

Lange also admitted that her fourth and last season on the show was her "absolute favorite." She also revealed to E! News that she is still open to the idea of being cast for the show's upcoming seasons. 

With Lange's departure from the show, comes the arrival of new faces and characters to "American Horror Story: Hotel."

The outlet reported that Lady Gaga, Matt Bomer, and "30 Rock" star Cheyenne Jackson are joining the show for its upcoming season.

Little is still known about Bomer and Jackson's characters and what roles they will be playing for the season.

When asked if Bomer would get into a romantic relationship with Lady Gaga's character, the "White Collar" star was "notably noncommittal," described IGN.

Meanwhile, "American Horror Story" alums were interviewed during the PaleyFest and were asked if they will be back for the next season. 

Denis O'Hare hinted that he would still be around, but refuses to confirm. Michael Chiklis said that being friends with Murphy, he would be willing to come back for the show whenever he needs him.

Finn Wittrock and Evan Peters both expressed interest in coming back for the show. 

"American Horror Story: Hotel" will debut in October on FX.
