Anne-Marie's rendition of 'Our Song' on Saturday's (September 17) episode left fans of The Voice UK stunned.
The crowd began chanting Anne-Marie's name hoping for a special performance. After two audience members shouted "Sing for us Anne-Marie," the crowd began chanting her name.
After some thought, the judge dutifully obliged, giving the live audience a performance of the song she recorded with One Direction member Niall Horan.
The Essex-born singer gave a stunning rendition of the slow-burning ballad, which appears on her second studio album, Therapy.
"I just cried at Anne Marie singing on The Voice," one Twitter user said.
"You just make me smile and happy when I watch you on The Voice," said one user, "That song was wonderful, and I love that version."
Another post saw a fan saying: "Every episode of The Voice makes me love Anne-Marie more."
"Anne-Marie sang 'Our Song' at The Voice and it was the one [show] I wasn't at,' says one fan, "Oh my God, I'm so sorry."
Following the performance, all other judges congratulated the singer, with Jones stating that the song was "really beautiful." Olly Murs gave her a standing ovation, while will.i.am said the song was "really nice" after asking Anne-Marie when she wrote it.
Kai Benjamin, a Cornwall rapper, wowed all four judges with a rendition of Ariana Grande's '7 Rings.'
After a lot of competition from the other judges, the 18-year-old chose Anne-Marie to serve as his mentor.
The Voice UK will continue on ITV next Saturday (September 24).
