Duffy thinks troubled stars like Britney Spears and Amy Winehouse are good role models.

The 'Mercy' singer believes it is healthy for fans to see their idols' flaws
because it shows everybody has problems in their lives.
She said: "In a really weird way, I think those kind of people show others
it's all right to be human - for all their faults."
Duffy, 23, says she has not always been a good girl, but is happy with her
current quiet lifestyle.
She added in an interview with Clash magazine: "I've made a lot of mistakes
in my life, so don't say I'm some kind of clean slate, virginal angel. But
I've not got any issues right now, which is good."
