"You can only imagine the amount of times I thought about writing this. The way I would write it, how I would feel thereafter. Well, not entirely sure why now is the right time, and what it is that feels exciting and liberating for me to talk. I cannot explain it," she began.
"Many of you wonder what happened to me, where did I disappear to and why. A journalist contacted me, he found a way to reach me and I told him everything this past summer. He was kind and it felt so amazing to finally speak. The truth is, and please trust me I am OK and safe now, I was raped and drugged and held captive over some days," she revealed.
"Of course I survived. The recovery took time. There's no light way to say it. But I can tell you in the last decade, the thousands and thousands of days I committed to wanting to feel the sunshine in my heart again, the sun does now shine. You wonder why I did not choose to use my voice to express my pain? I did not want to show the world the sadness in my eyes. I asked myself, how can I sing from the heart if it is broken? And slowly it unbroke."
Duffy said that in the coming weeks she'll post a "spoken interview" further explaining her ordeal.
"Please respect this is a gentle move for me to make, for myself, and I do not want any intrusion to my family," she said. "Please support me to make this a positive experience."
Fans have today praised Duffy for her bravery.
