Amy Winehouse seen with white blob up her nose

Troubled British singer Amy Winehouse has been snapped with a white blob up her nose, after spending two hours partying with a fan backstage after her gig in Blackpool.

According to British newspaper The Sun, 'Rehab' singer Amy spotted a young girl with a copy of her trademark hairdo and jumped off stage to hand her earrings - she then grabbed her by the hand and invited her back stage.

When the duo appeared again onlookers were left wondering if Amy had fallen back into her wild ways.

One said: “Amy had been in high spirits all night and clearly had blobs of a white powder up her nose.

“She looked a bit wide-eyed too.

“I can only imagine what the girl’s mum will make of it all.”

A fan at Tuesday’s show said: “She turned up an hour late, but she soon won us over.”
