Duffy has made an unexpected return in a new social media video - ten years after a horrific kidnap ordeal.
In a video shared to TikTok, the 40-year-old singer - real name Aimée Anne Duffy - can be seen lip syncing to a remix of her noughties hit, Mercy.
The clip was posted on Emotion HQ's account, which teased that the remix will be released soon.
The accompanying caption read: “Some of you asked if Duffy was really doing a UK Garage remix with us… #duffy #newmusic #ElectronicMusic #ukgarage #dancemusic #remix.”

The Welsh star’s meteoric rise to fame from unknown talent show hopeful to Grammy Award winner was like something out of a story book.
It took a nightmarish turn however when she revealed in 2020 that she had been held captive over a four-week period.
According to Duffy, she was drugged at a restaurant where she had been celebrating her birthday, before being abducted abroad and raped, and then flown home where she was held captive in her own home.
She said that she had been too terrified to go to the authorities in the immediate aftermath, for fear of her attacker locating her.
Duffy further shared that the incident had not only put the brakes on her promising career, it had left her estranged from her family and loved ones as she struggled to cope.

As a result, she said she moved house five times before she started to feel anywhere near safe again.
This was short-lived however it seems, as she reported the incident to the police twice after someone threatened to sell her story for blackmail, and a second after three men broke into her home.
Duffy said: “In the aftermath I would not see someone, a physical soul, for sometimes weeks and weeks and weeks at a time, remaining alone.
“I would take off my pajamas and throw them in the fire and put on another set. My hair would get so knotted from not brushing it, as I grieved, I cut it all off.”
Of her decision to finally speak out, she said: “I am sharing this because we are living in a hurting world and I am no longer ashamed that something deeply hurt me, anymore.
“I believe that if you speak from the heart within you, the heart within others will answer. As dark as my story is, I do speak from my heart, for my life, and for the life of others, whom have suffered the same.”
She continued: “I have no shame in telling you either I had spent almost ten years completely alone and it still burns my heart to write it.
“I owe it to myself to say it, I feel obliged to explain how challenging recovering truly was and to finally disclose it. I hope it comforts you to feel less ashamed if you feel alone.”
Explaining that her main hope was to gain some closure, she concluded: “I can now leave this decade behind. Where the past belongs. Hopefully no more ‘what happened to Duffy questions’, now you know … and I am free.”
