Bruno Mars has given his new single its first public airing.

The music maestro is releasing the track 'Locked Out Of Heaven' as the lead single from his forthcoming new album 'Unorthodox Jukebox'.

The 'Grenade' man is releasing the album on December 10 and a day later in the US and he has now premiered the first cut from the album.

'Locked Out Of Heaven' was debuted on radio and Mars also uploaded the track to his official YouTube page.

As previously reported, Mars recently admitted that his record label bosses have told him in the past that his music "sucks" and that his desire to attempt different genres makes him hard to market.

He said: "I've had big record label presidents look me in the face and say, 'Your music sucks, you don't know who you are, your music is all over the place, and we don't know how to market this stuff. Pick a lane and come back to us'."
