Madonna releases violent teaser for mysterious 'Secret Project'

Madonna has released a short clip of 'Secret Project,' a mysterious endeavor that she has kept in wraps.

In the video, the 54-year-old pop diva is seen standing over a dancer - who resembles her toyboy Brahim Zaibat - with a gun before apparently pulling the trigger, the New York Daily News reported.

Another scene shows a man being violently slammed to the floor by four topless men before hurtling against glass, as the singer, wearing an S and M-style mask, makes violent movements in another room.

Clips of a ballet dancer dancing in undies are spliced with photos of a room littered with bodies and the singer being dragged along the corridor by cops.

The black and white footage is the first glimpse of the project that Madonna has been working on with photographer Steven Klein.
