Little Mix have teased fans once again over their new video.

The girl group are set to unleash the clip for their latest single 'DNA' on Friday (October 19), which is due to be taken off their debut album of the same name.

The X Factor 2011 winners recently unveiled images from the video's recording and it showed the girls sporting an edgier, darker look.

Speaking to Capital FM, Little Mix said that they enjoyed playing characters in the video and twisting the theme of "love and obsession".

Leigh-Anne Pinnock said: "I loved being able to play a character. To play this obsessed weird person that's just crazy over this guy."

Jade Thirlwall added: "Basically we took the theme of the song - the whole love and obsession thing - and just took it to an extreme. But that's all we're saying!"
