Phantom of the Opera's music just got even more beautiful.
In the duet, Clarkson, 32, and Groban, 34, take on the characters of Christine Daae and Phantom, which will be featured on Groban's upcoming album Stages.
Stages is set to drop on April 28, but for now, take a listen to the ballad here.
Clarkson tweeted to Groban back in March saying, "So excited about this new album 4 you! What an amazing collection of songs!! Thanks for asking me."
He replied back, "I'm so honored you said yes!! What a joy to finally work with you on a song that means so much to me. You sound SUPERB!"

The gushing hasn't stopped as Groban tweeted at his duet partner with one simple but meaningful word on Tuesday, "Bravo!"
Stages also features "Bring Him Home" from Les Miserables and "Over the Rainbow" from The Wizard of Oz.
