Amy Winehouse diagnosed with impetigo

Troubled singer Amy Winehouse has been diagnosed with impetigo, her rep has confirmed.

"Amy has been diagnosed with impetigo - which she has been told can be highly contagious. Because of that she's been put on antibiotics and may have to stay home alone for the next few days," said the rep.

The disease, a bacterial skin infection that causes pimple-like lumps – and is "is highly contagious, and scratching or touching the sores is likely to spread the infection to other parts of the body as well as to other people," according to medical experts.

The singer, 24, was seen trying to mask the swollen, bruised left cheek with make-up as she moved into a new home in East London last week, which prompted her to seek emergency medical medical treatment.

But despite her lumpy face - the singer's feeling "fine," says a pal of the 'Rehab' star. "She's not hiding away. She's never been one to care what people think."
