Carrie Underwood and Dan + Shay just dropped a new collaboration, "Only Us."

The song, which was produced by Dan Smyers, is from the upcoming "Dear Evan Hansen" movie.

Dan + Shay spoke out about their duet on social media, saying they are "super fans" of Underwood. "It's always been a dream to collaborate with her," they wrote, adding that the duet is "quite possibly the coolest thing that’s ever happened to us."

The trio also released an in-studio performance video of the song that features footage from the upcoming film.

Other artists appearing on "Dear Evan Hansen (Original Motion Picture Soundtrack)" include Sam Smith with Summer Walker, SZA, FINNEAS, Tori Kelly and more.

The 16-track album will be released on Sept. 24 -- the same day the film will be released nationwide.

"Only Us" is available to download or stream now.
