The singer, whose real name is Victoria Hesketh, praised Lewis’s voice, but said she lacked any personality.

“My music is much more than that,” she told The Sun newspaper.

“Surely having ‘The X Factor’ is somebody with amazing talent and personality. You look at Leona Lewis and she’s got an incredible voice but I don’t see anything else.

“Everyone on that show goes crazy when someone manages to hit a high note. It’s so one-dimensional.”

Hesketh, who releases her debut album ‘Hands’ in June, entered Pop Idol as a teenager.
