X Factor star Leona Lewis has debuted her new single Trouble, which fetaures US rapper Childish Gambino.
But it's not just Leona and Childish who've worked on the track - Emeli Sandé wrote Trouble and it was co-produced by Naughty Boy and Fraser T Smith.
Trouble is the follow-up to Leona's 2011 hit Collide.
"[Trouble is] very deep and has amazing lyrics that are from the heart. It was great collaborating with Emeli because she really gets where I come from," Leona said earlier this year.
The track is the second single to be taken from her upcoming album Glassheart, which will be released in the UK on 15 October.
Trouble is due for release 7 October.
So what do you think - is Trouble going to be a smash hit?
