Madonna has unveiled a new teaser trailer for her mysterious 'Secret Project'.

The Queen of Pop has been teasing the enigmatic campaign, which has been created in conjunction with photographer Steven Klein, for some time.

The 'MDNA' star has now released a new promotional video for the project, which sees a number of male and female models remaining stationary.

The camera pans across them until it reaches Madonna, who then knocks over a table with force.

The singer can also be heard in overlapping voiceovers during the video, concluding:

"I feel that people are becoming more and more afraid of people who are different. People are becoming more and more intolerant."
