Closer was a demo Camila recorded for American DJ/production duo The Chainsmokers, which was later given to Halsey. A 10 second snippet of the demo featuring Camila's vocals was leaked.

Trivia Edit

  • Camila was asked to be on the song after she recorded the demo, but turned it down because of Fifth Harmony's second studio album 7/27 being released soon after the song would've been released.
