Rachel Bloom, star of The CW's Crazy Ex-Girlfriend, said Josh Groban will appear on the show in Season 3.

"Hey! @joshgroban is gonna be on #CrazyExGirlfriend!" she posted Monday night alongside a video of the two.

Groban shared the same video with the caption, "Oh hey @Racheldoesstuff. Thanks for having me on your brilliant show! I know it's secret but this is a DM right?"

The show is known for its cast of Broadway luminaries and stars Donna Champlain (Billy Elliott, Sweeney Todd), and featured Tony-nominee Santino Fontana in its first two seasons. There are elaborate musical numbers in every episode of Crazy Ex-Girlfriend.

Season 3, debuting on Friday, Oct. 1, will focus on Bloom's character Rebecca Bunch and her life after being left at the altar by Josh (Vincent Rodriguez III).
