Duffy, who is one talented singer is very thankful that her sister broke her nose when she was younger because it is the reason she has her trademark voice.
She tells ITV.com, "When I was four-years-old my sister blindfolded me and chased me round the garden. She forgot that I was blindfolded and I ran into a fence and broke my nose. I remember it as well because it was so extreme, and I was really worried.
"I went to the doctor, I had broke my nose, everything was a mess. I was screaming and upset, and the doctor said, 'Don't worry. One day, she'll be a really good singer.'
"So, I don't know - maybe I owe it to my sister for breaking my nose!"
Not only is she thankful that her sister broke her nose, we're all thankful because she has a rockin voice!
