Maren Morris had to record her duet with Teddy Swims when she was ill.

The 33-year-old singer has teamed up with fellow musician Teddy, 31, on the new track 'Some Things I'll Never Know' but was struck down by an illness on the only day she could be in the studio and is hoping that the "heartbreak" she felt in that moment added something to the sound of the song.

She told People: "I was a little bummed that it was the only day I could do the vocal and I was sick. And so [co-writers Julian Bunetta and John Ryan] were assuring me that it still sounded good, even though I felt so stopped up in it. But it maybe added to my heartbreak in the vocal."

The 'My Chruch' songstress went on to add that the recording process was an experience that she will "never forget" and she felt as if she could see God whenever she was haromising with Teddy and described the new track as a "beautiful song" that resonates with her.

She said: " It was definitely an experience that I’ll never forget, just because I didn’t think about hitting certain notes perfectly. I wasn’t overthinking or over analyzing. I was just so in the emotions of Teddy’s vocal, and just found my footing throughout the second verse, and just feeling like you see God or something when you get to harmonize with a vocal like Teddy’s.

"It just resonates — the meaning of the lyric resonates with me so much right now. It’s just such a beautiful song with or without me on it, but I’m obviously so honored to be a small part of this one."
