'Crazy Ex-Girlfriend' season 2 cast, spoilers: Actors from 'Pitch Perfect' and 'Jane the Virgin' join series

"Crazy Ex-Girlfriend" will be featuring two more stars in its upcoming season this fall. They are Brittany Snow from "Pitch Perfect" and Yael Grobglas from "Jane the Virgin." However, the appearances will just be for a few episodes for now.

Snow will be joining the musical series as Anna for three episodes. Her character is a "hip and cool" beauty stylish/entrepreneur. The character comes from Los Angeles and is in town to shake Rebecca's (Rachel Bloom) life up. As expected, she will also be doing a musical number on the show, TVLine reported.

Meanwhile, some of Snow's upcoming movie projects include "Pitch Perfect 3" and "The Potters." She also made an appearance in "Workaholics" and lent her voice in "Trip Tank," both from Comedy Central.

Bloom, who is also the co-creator of the series, announced the news on Twitter via a song number.

Groblas will also be crossing over to "Crazy Ex-Girlfriend" in a single-episode appearance, which will be in the fourth one. She will be playing the role of Trina, a young businesswoman who employed Rebecca to represent her company. The two characters will then intertwine, which will change Rebecca's life. Fans can also expect a musical number to be performed by both Groblas and Snow.

Bloom also announced Groblas guesting on Twitter.

Looking back, "Crazy Ex-Girlfriend's" first season ended with Josh (Vincent Rodriguez III) and Rebecca finally getting together, after a whole season of trying. However, she also hooked up with Greg, for whom she realized that she had developed a romantic feeling. Greg, on the other hand, also had the same feeling but decided to let Rebecca go to whom she really loved, Josh.

Fans are expecting that the upcoming season will be more interesting. Bloom revealed that her character will be more open than before.

"Crazy Ex-Girlfriend" season 2 will premiere on Oct. 21, on The CW.
