and  are the musical duo you didn’t know you needed -- until now! On Wednesday, the Welsh actor dropped the pair’s duet, "Say Something." Evans and Kidman cover A Great Big World and Christina Aguilera's GRAMMY-winning single for his upcoming album, . 

Evans begins the hit ballad with his smooth tenor, before he trades verses with Kidman, who enters the song in verse two. The duo, who starred together in , carry the rest of the piano-led ballad with each other.  

The  actor revealed that the idea to have Kidman on the single came after an evening at her house in Australia.

“I knew that Nicole loved to sing, so she was joining in,” he said in a statement about the evening.  

From that moment, the idea to have the  actress on his album was born.  

"I already had that song in my head, because I knew that it would fit Nicole's voice very well, that I could blend our voices," Evans said. "So I sent them the track, and Keith was like, 'Genius – I couldn't have thought of a better track.

Kidman’s vocals were recorded at Urban’s Nashville studio. "He sent me a little video of her in the booth recording. And she loved every minute of it. She was so grateful that I'd asked her. I was, like, grateful? You have no idea how grateful I am! But she's a lovely woman, and a friend, and very generous with their time. To do something like this was really special," Evans shared.  

The actor took to his Instagram to share a video of him and Kidman recording the song.
