Leona Lewis unveils new single 'Fireflies' lyric video
The singer released the audio for the track - which appears below - on her official YouTube channel.
"This song is really special to me, really important and has such a meaningful and powerful message behind it," she recently said of the track.
"I think in the run-up to Christmas it's going to be a really powerful song. I'm just really excited about it."
'Fireflies' marks the second single from Lewis's latest album Glassheart, which entered at number three in the charts earlier this month.
The star previously revealed that she is planning a US tour next year, adding: "I've never toured over there so I can't wait."
