Welsh singer Duffy says 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 Winehouse, Digital SPY reports.

"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 realized that kind of behavior is just not me and never did it again."
