Amy Winehouse may have been dead for 6 hours before being found

Amy Winehouse may have been dead for up to six hours before she was found dead on her bed by a security guard.

The star, 27, last spoke to her security team at 10am on Saturday. She was found at home in Camden, North London, at 4pm, but medics said she’d been dead several hours.

Amy’s doctor had examined her the evening before her death - and gave her the all clear, reports the Sun.

The singer was having regular check-ups because her drink and drug battles had left her so frail.

"The doctor was happy with her condition. When he left on Friday night he had no concerns. Less than 24 hours later she was found dead," the daily quoted a source as saying.

"Amy’s health has been very fragile and she has been having a series of check-ups," the source added.

Amy was found dead in bed at her home by her security guard Andrew Morris just before 4pm on Saturday.

She had been alone in her apartment apart from one security guard, who called emergency services after finding her in the bed not breathing, according to her friend and PR man Chris Goodman.
