Leona Lewis performs acoustic version of new single 'Trouble' - video
The singer will release new cut 'Trouble' on October 8 and has uploaded footage of herself performing a stripped-back version of the track.
The black and white footage sees Lewis singing the track in the studio, while accompanied by a pianist and a violinist.
The radio edit of 'Trouble' features US rapper Childish Gambino and was co-penned by Emeli Sandé.
'Trouble' serves as the lead single for Lewis's third studio album Glassheart, which will be released in the UK on October 15 and a day later in the US.
Lewis recently topped a Digital Spy readers poll for the album they are most excited to hear this year.
