Calvin Harris has started teasing fans about his upcoming team-up with Jessie J. The Scottish DJ shared a picture of his computer screen featuring the final edit of the song that he has been working on this week. Jessie confirmed to Capital FM last week that she and the 'We'll Be Coming Back' producer have recorded a song together from her new album, and both stars have tweeted each other about the highly anticipated collaboration. "Tweakin this @jessiej song for the last time… love this track!" Calvin tweeted this afternoon (5th June), while Jessie soon added: "Boooooom yeah buddy!" The song Jessie recorded with Calvin is for her second studio album and is confirmed to be the only track from the record that she didn't write herself.Capital
