Ex-manager claims Amy Winehouse spent £3,500 a week on drugs

Amy Winehouse's former assistant manager – who says he had an affair with the singer – claims she was getting through £3,500 a week on drugs.

Alex Haines, a junior assistant manager to the star, also believed that Winehouse was suffering from bulimia while he was working with her in 2007.

The junior manager – who says he had an affair with the singer while her husband Blake Fielder Civil was in prison – told News Of The World about the singer's alleged spending on drugs.

"She had to have a heroin and crack pipe near her or she freaked out," he explained. "She’d keep taking drugs until she passed out. I reckon she spent £3,500 a week on them.”

Haines added that her addiction was made worse by the eating disorder.

"Amy suffered from bulimia, which is why she looked so thin. She would have a massive McDonalds and then throw it all up in the bathroom. I found my toothbrush covered in sick, and asked her about it," he said. "She went really sheepish but told me she suffered from it for a long time.

"Several times I went into her bathroom and saw sick all over the sink. She lived off Crunchie bars - up to 10 at a time - packets of Haribo sweets and bottles of orange Lucozade Sport. Her heroin problems made her crave sugar."

The assistant manager who quit working with the singer in May as it appeared her husband might be released from prison, also shed light on why Winehouse's much touted collaboration with Mark Ronson on the theme for recent James Bond film 'The Quantum Of Solace' never materialised.

"Mark Ronson had prepared a backing track based on [composer] David Arnold’s 'Quantum Of Solace' score," he recalled. "But when Amy heard it, she said, ‘I want a tune James Bond would dance to. That sounds like something fucking James Bond gets into an elevator to’."
