Amy Winehouse cut a nasty sight when she revealed an unpleasant-looking rash that she wouldn't stop scratching.

The Rehab star told photographers that her body is covered in an itchy rash and was happy to show off her spotty arms.

Later she went one step further as she revealed her blotchy back while lifting up her top to relieve the irritation.

Amy famously suffered a bout of the highly infectious skin disease Impetigo earlier this year, which left her face covered in raw scabs.

Despite her obvious discomfort, Amy seemed in good spirits as she met up with friends in her local for some drinks, including photographer pal Blake Wood, also known as 'Other Blake.'
