Next week's Glee episode is going to be all about Broadway tunes! Rachel (Lea Michele) and Blaine (Darren Criss) will be performing a duet together, and the two stars are giving us a sneak peek at what we can expect.

Lea and Darren recorded a behind-the-scenes video from the set of next week's Season 5, Episode 15: "Bash," where they talked about how excited they are to perform "Broadway Baby" fromFollies together.

"We are doing this song, Chris is doing [Follies' 'I'm Still Here'], and later, Darren is singing [Into the Woods'] 'No One Is Alone,'" Lea reveals about their Broadway-centric shooting day. "I'd say this is probably my type of day at Glee."

Darren couldn't agree more about enjoying the day. "To be sentimental for a second, I'm really happy that I got to sing this song with you," he adorably tells Lea. "We're like Broadway babies. I didn't grow up on Broadway, but I grew up loving Broadway." Aww!

We can't get enough of Darren and Lea's voices together, so we're ridiculously excited for this episode. It's also interesting to know that Lea prefers recording show tunes to pop songs. As far as we're concerned, it's a treat to hear Lea perform any type of song!

What do you think of the song selection from "Bash"?
