Amy Winehouse Has 'Suspicious White Substance' Up Her Nose

Not one to stay out of the limelight, Amy Winehouse has been photographed in Camden with a suspicious looking white substance up her nose.

The troubled singer had been DJing at the highly intimate Monarch Club in the North London district last night when the army of paparazzi who follow her captured the images below.

Winehouse tried to cover her face with a cardboard box and a lampshade but unfortunately it was to no avail.

The 24-year-old courted controversy earlier in the week when she went on a pub crawl in Camden after she had reported to the private health clinic where she is being treated for her drug addictions.

She was also pictured apparently slapping one of her security men outside her home. To see the pictures of Winehouse from last night, click through below:
