Noah Cyrus and Labrinth's duet came about as a "mistake".
The 16-year-old singer - who is the younger sister of Miley Cyrus - was originally meant to record 'Make Me (Cry)' alone, but she fell in love with the idea of having the British star appear on the track, which he wrote, after his vocals accidentally came in during recording.
She recalled: "Originally it was just me on the song, and then just by mistake his vocal came in and I was like, 'Oh, my God, you have to stay on it.
"I think that was a really special moment for us because we were so excited, jumping around the studio like, 'Oh, my gosh, this song is so sick!'"
The 'Doc' actress has spent two years working on her album, but was initially hesitant because of the success of her father, country singer Billy Ray Cyrus, Miley, and their rocker brother Trace.
She told Rolling Stone magazine: "It's so exciting because I feel like I can finally talk about it now.
"In 2014, when the 'I Forget When We Were' album came out by Ben Howard, that was really inspiring to me.
"I just started getting this drive to want to write and sing and start my own album."
Though country music has been a big influence on Noah because of her father, she insists her own record has a very different sound.
She said: "In my family, I grew up listening to my dad sing country music, but [the album] is definitely different from what I was raised listening to."
And the teenage star is thankful to have a lot of support from her famous family, with Miley telling her she needs a "thick skin" in the public eye.
She added: "Miley always says, 'Don't ever look yourself up or read your comments, 'cause you're gonna see stuff that you don't want to see.
"That's the best advice ever. If it's making me happy, then it's working.
"My dad has learned all of the songs that I've sent him. He put it on his computer, on his jukebox, on his phone. He still has a Blackberry, by the way. But everybody's been so supportive."
