Justin Bieber Unveils New Song 'Recovery'
Teen idol hints at Selena Gomez split when explaining meaning of tune...
"At the time, I was going through a very hard break up and when you're going through stuff like that you think that the world is just gonna end. Then you wake up the next day and realise that life has to go on."
He added: "Recovery is that feeling you get when you start to move on and make things better for yourself because yesterday is gone and tomorrow is here."
Bieber will premiere a new song every week in the lead up to the release of his new film Believe, which hits cinemas on Christmas Day.
Recovery is available to buy now.
