Netflix will see the return of "Unbreakable Kimmy Schmidt" as it launches its second season.

The new season of the hit American sitcom will follow Kimmy (Ellie Kemper) once again, as she tries to live in a strange new world and cope with her ever-confusing feelings.

Veteran comedian Tina Fey, co-creator and co-writer of the show, shared with Deadline that the new season will feature more backstory for Titus (Tituss Burgess) and that Dong (Ki Hong Lee), Kimmy's love interest, will definitely be back. Kimmy will apparently also struggle with the end of her first relationship with Dong.

The Netflix series will reportedly show more bunker scenes in the next season, which means fans will get another chance to see how Kimmy lived her life while she was trapped, and hopefully another appearance by Jon Hamm, who played Richard Wayne Gary Wayne.

Several actresses have also been spotted on the set of "Unbreakable Kimmy Schmidt," which means more guest stars will appear on the show.

Anna Camp ("Pitch Perfect") was seen filming a scene with Jane Krakowski (who plays Jacqueline Voorhees) and rumor has it that she's playing the role of her sister.

"Girls" star Zosia Mamet has also been seen on set looking chic in a black leather jacket and a black hat, but details on her character has not been made public.

All these cast news are very exciting, but perhaps the most exciting of them all is Fey herself returning to guest star on the show.

Fey was seen on set, filming what looks to be a drunk scene, with Kemper. Based on the photos, Fey looked downright wacky as Kemper tried her best to support and carry her.

Fey also had a recurring role on the first season of the show as an incompetent prosecutor named Marcia, but it is unclear whether her role will remain the same or will be an entirely new character.

"Unbreakable Kimmy Schmidt" season 2 is currently in production and will air sometime in 2016.
