Kelly Clarkson remembers singing karaoke with Amy Winehouse

Kelly Clarkson has recalled how she once did karaoke with Amy Winehouse before the late singer became famous.

The talk show host told the story while she was interviewing actress Marisa Abela, who plays Amy in Sam Taylor-Johnson's new movie, Back to Black.

"It was like before she became Amy Winehouse," Kelly said. "I don't think she had a record deal or anything at that time, but we all went to karaoke, and she sang Etta James and I was like, 'Wait, what?' It was like she, just from the jump, had such a presence about her voice. It almost became, like, more of a character, too, like with herself throughout her career."

Amy eventually released her debut album, Frank, in 2003. Her second album, Back to Black, was released in 2006 and became one of the best-selling albums in UK history.

Amy died in 2011 at the age of 27, after struggling with addiction.

Marisa has spoken of how hard she worked to try and use Amy's voice during the filming of the new biopic.

"When I was prepping for the film, it was about getting a sensory experience of where Amy would have been, and how she would've felt," she told Vanity Fair. "I was gonna work as hard as I possibly could to get to that place where I am singing as Amy. Not like Amy."

Back to Black is set for release in U.S. cinemas on 17 May.
