Singer-songwriter Bruno Mars has explained that the accompanying music video for new track 'Young Girls' will surprise his fans.

Speaking to MTV News about his decision to release the track, the 'Marry You' sensation revealed that he's expecting the visuals to signify a darker and "more aggressive" direction, which will relate to his newly released album, 'Unorthodox Jukebox':

"I felt 'Young Girls' was good. 'Locked Out of Heaven' was something brand new I tried in the studio and it felt like the right thing to do. None of these things are planned, which one goes first, which one goes second."

"One day I wake up and I say, 'You know what? I want the world to hear this song that I wrote called "Young Girls," and I put it out. Every day I'm thinking about the video. It's going to be something I've never done before, I promise you that."

Mars is set to perform 'Young Girls' on December 12 during an eight-hour live stream for Viacom's 12/12/12 celebration.
