Another relapse for troubled Amy Winehouse. The Grammy Award-winning singer had reportedly snorted cocaine at a party with Sir Bob Geldolf's daughter nearby.

Winehouse, 24, apparently sneaked off to a bathroom to snort the drugs, with 17-year-old Pixie Geldolf in the next-door room.

A source says that the "Rehab" singer had complained to the partygoers at her home about her drug habit. Winehouse was said to be worried that her addiction could make her lose her looks and husband.

She reportedly said after inhaling cocaine, "I've been told I'll lose my looks over this - but I can't give it up! I'm told my scars might never heal. My dermatologist says it's a result of the drugs and it could spread to other parts of my body if I don't quit."

"What will I do if I lose my looks? Blake will never love me like that."

The source tells to News of the World, "Not only was it obvious what she was doing but I could see her. I was waiting to use the toilet and could see Amy through the door.

"It's sad to see one of Britain's hottest talents kneeling on the floor of a bog and snorting drugs. She dabbed up the last few bits of powder, making sure she got ever last bit, from the lid."

"On top of the drugs she was drinking heavily. Bottles of rum and coke were lying around - she was clearly worse for wear."
