Duffy made an unexpected return to the limelight last month after she shared troubling details of her past.
The 'Mercy' singer revealed that the reason for her absence from the music scene for so many years was because she had been "raped and drugged and held captive for some days".
Now, following the harrowing ordeal, she has unveiled a new song which was played on BBC Radio 2 last night.
She announced the release of 'Something Beautiful' - which she says she doesn't plan to release - with an open letter to DJ Jo Whiley on Instagram. In it, she said that she was finding it difficult to open up about her ordeal.
"You may have read the words I wrote a few weeks back, I do feel freer," she wrote. "Tried to follow up with a spoken interview, but it’s harder than I thought, I will follow up in writing soon.”
Of the song, she added that her record label were unaware of what she was doing, saying: "I just thought a little something might be nice for people if they are at home, on lockdown."
