MUMBAI: A never-heard before track featuring Justin Bieber and his former girlfriend- Selena Gomez was leaked online.

The track by the Canadian crooner appeared on Drake’s OVO Sound Radio. Perhaps the biggest surprise, however, came when the single featured Gomez.

Titled ‘Strong,’ the song can be described as a stripped-down duet. However, the track disappeared soon after fans of both singers went into a frenzy on Twitter.

However, both singers have not yet commented on the track, and there is no official word on whether or not the song will be featured on Bieber's upcoming album, ‘Purpose’, which will be released on 13 November.

In recent weeks, both Gomez and Bieber have talked openly about their past relationship in separate interviews.
