Bruno Mars has unveiled the video for his latest single 'Locked Out of Heaven'.

The music maestro is releasing the track from his forthcoming album 'Unorthodox Jukebox', which is due to be released on December 10.

The record will mark the follow-up to his successful debut album 'Doo-Wops & Hooligans', which was released in 2010.

Mars has now released the promo clip for 'Locked Out of Heaven', which evokes a vintage feel via camera effects and a 70s setting.

The 'Grenade' man tweeted that he wanted his fans to see the video first - not television audiences. He said:

"Everyones telling me to wait for a big primetime premiere on TV but you know what i says to em? I says NO! My fans desoyve to see it foist."
