Duffy vows not to end up like Winehouse

Duffy has insisted that she will not make the same mistakes as troubled star Amy Winehouse.

The Welsh singer revealed that she learned her lesson about the effect of alcohol at an early age and will not be tempted to fall into the same traps as Amy.

"People compare me to Amy a lot but I don't think I'm in any danger of suffering similar pitfalls to her," Duffy explained.

"One time, when I was 14, I had a few drinks at a small jazz club. It was all very illegal. After some fortifying alcohol I got on stage and sang my heart out. Afterwards a man said I was caterwauling. I was so mortified, I realised that kind of behaviour is just not me and never did it again."

Winehouse faced a backlash from fans last year when she behaved erratically at a number of gigs. In January, she decided to seek help for her drug and alcohol problems and entered rehab for a short stint, but recent reports have suggested that she is already back to her old ways.
