Amy Winehouse ''went mad'' at her father Mitch Winehouse after he stopped her attempts to sneak cocaine into rehab, it has now emerged.
The late singer, who had a high profile drug and alcohol addiction throughout her life before her death, is said to have tried to sneak drugs into the London rehab clinic via a teddy bear and a bouquet of flowers.
Mitch, who blames her ex-husband Blake Fielder-Civil for Amy's drug addiction, has revealed the shocking revelations in a new memoir, 'Amy, My Daughter'.
Writing in the memoir, he explains: ''Amy had an incredible power of recovery, given the quantity of poisonous substances involved. But a few days later, I had a call from the hospital to tell me one of Blake's friends had smuggled drugs into the hospital, crudely stuffed inside a teddy bear.''
''On Monday, June 16, Amy had another seizure. She was taken to The London Clinic. We had security guys working shifts to look after her by this time and the next day I took a call from one of them to warn me that a package was on its way.''
''I jumped in my cab, and reached the clinic just in time to see a known drug-dealer with a bunch of flowers for Amy. The security man searched the bouquet and found a rock of crack cocaine. Amy went mad when she found out we'd intercepted the drug.''
Mitch also discusses the family's disappointment after the 'Rehab' singer secretly married Blake during a holiday to Miami in May 2007.
He wrote: ''I couldn't say anything to her. I pretended I couldn't hear her properly and hung up. I was beside myself with sadness for Janis.'
''It was later that year, on the evening of Monday, August 6, when Amy had her first seizure. She was alone with Blake. He put her in the recovery position but instead of calling an ambulance, he phoned Juliette, one of Amy's oldest friends, who drove her to hospital.''
''Now I knew I'd been wrong in thinking Amy was stronger than Blake. It appeared to be the opposite. As the terrible months that followed were to make clear.''
Meanwhile, Amy Winehouse reportedly "begged" her ex-husband Blake Fielder-Civil for a baby called Lucky.
The letters she wrote to him are allegedly signed "your wife" - despite the fact that they were written after they were divorced.
