Amy Winehouse proudly shows off her healthier new body... as ex-lover tells of her 'bulimia and sex addiction'

Amy Winehouse looked healthier and happier than she has been in years, as she tucked into lunch on her Caribbean holiday.

Polishing off nearly a full plate of food, the chart-topping singer's clear skin and shiny hair spoke volumes about her improved diet and lifestyle - a stark contrast with the excesses of her life in London, the full extent of which was revealed by an ex-lover today.

Alex Haines, who had a relationship with Winehouse while her her husband, Blake Fielder-Civil, was in jail, revealed graphic details of her self-harming, and sex and drug addictions.

Haines, 23, also spoke of how he discovered Winehouse had an eating disorder, and revealed her fears of joining the '27 Club' - a group of musicians, including Jimi Hendrix and Kurt Cobain, who died at that age.

In an interview with The News Of The World, Haines claimed that the 25-year-old spent £3,500 each week on drugs. 'She had to have a heroin and crack pipe near her or she freaked out,' he said. 'She’d keep taking drugs until she passed out.

'At one party Amy wanted to prove she was used to cocaine. So she did a line that was 20 centimetres long to show she was a big user.'

Haines, who was Winehouse's assistant at the time, claimed that the singer would team her breakfast of tea and toast with crack. 'When Amy woke up the first thing she’d ask was, "Where’s my pipe?"' he said.

He spoke of how the 'Rehab' star would make crack pipes by putting foil on top of plastic bottles to burn the drug.

'When Amy ran out of the drug it she would cut the bottle in half and sit there on the floor completely wired, scraping the inside to get the residue with a screwdriver.

For such a small girl she had amazing drugs tolerance. It was scary what she could do.'

Winehouse's self-destructive streak also extended to self-harming. 'Cutting herself was her favourite pastime,' said Haines. 'It was my job to look after her. But it was impossible.

'The first time I saw her do it was after she told Blake we’d had a fling. She cut herself with scissors from shoulder to wrist.' he revealed, admitting that he didn't think Winehouse would survive the year.

Haines, whose affair with Winehouse began after her husband was jailed for GBH and perverting the course of justice. He claimed that the Brit Award winner was as addicted to sex as she was to drugs. 'It was like having my own little porn star. Amy was so dirty—she wanted sex all the time.'

Haines also spoke of an eating disorder, telling how the singer told him how she had suffered from bulimia for years.

'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.

'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 couple would argue over Winehouse's erratic behaviour. Haines told how Amy would talk of her future with Fielder-Civil with him, only moments after making love.

The guilt of their affair would eventually lead her to end the relationship, shortly before her husband's release from prison. 'She couldn’t cope with her own guilt,' said Haines. 'She told me, "Blake said we can’t speak to each other any more. You know I love you to pieces but we can’t see each other."'

Haines has not spoken to Winehouse since, but said of her: 'To me she wasn’t a star, but a sweet girl with a few problems. She needed rehab—and it’s great to see her getting better.'
