Pop queen Madonna, who was photographed holding a cigarette, has not started smoking again, her representative says.

The 'Material Girl' singer has stepped behind the camera to direct W.E. - the story of Britain's King Edward VIII - who abdicated the throne after falling in love with American divorcee Wallis Simpson.

'She was snapped on location holding a cigarette and a lighter, prompting reports that she had taken up smoking again, a habit she quit when she was younger,' reports contactmusic.com.

However, the spokesperson insists the gossip is not true and Madonna was merely holding a prop cigarette for one of the stars of the movie.
