Amy WinehouseAmy Winehouse has received a stark warning from doctors treating her for alcohol abuse at the Priory, reports say.

According to The Sun, the singer must quit alcohol for good or face a bleak prognosis. A source was quoted by the tabloid saying, "It's the last chance saloon for Amy. Doctors have come down hard on her because of the severity of her situation. It's a harsh reality but she had to hear it."

Both her boyfriend Reg Traviss and father Mitch Winehouse have been on hand to offer their support at the London facility, the paper said.

"They are worried about her. Mitch has been down this road before during Amy's drug addiction. But she is there of her own accord this time and wants to sort herself out," the source was also quoted as saying.
