The boy band, who starred in last year's Big Reunion, are releasing a track called 'King Of The World' ahead of their forthcoming tour.
Blue are famed for their pop tunes, however their latest song is said to be "stepping into soulful territory" and will feature lead vocals from Simon Webbe.
The lads are currently starring in their own reality show on ITV2, Blue Go Mad In Ibiza, and are looking forward to returning to the music scene. In March, they will kick off a 16-date tour in Portsmouth, Hants, and there is a new album on the cards too!
Band member Duncan James says: "A new TV show, album and tour mean that we are all looking forward to 2015. It's looking to be a great year and we are excited to share our newest chapter with the fans."
Simon adds: "Sixteen years later and we are still evolving as a band. We're proud of that. Music binds myself, Lee, Duncan and Anthony together, it means everything to us."
'King Of The World' is released on 2 March.
