'X Factor' judge Louis Walsh has branded the Spice Girls "very overrated", claiming that none of them can sing.
Walsh reportedly told Star magazine: "The Spice Girls are very lucky and very overrated. None of them can sing and their music is not half as good as Girls Aloud's."
"Spice Girls appealed to little girls. It wasn't good music - mums would buy the albums for their kids - it was all about the gimmicks."
Walsh, who recently rejoined the judging panel of 'The X Factor' after being axed from the show, also said that none of the Spice Girls were talented enough to have a successful solo career.
He claimed that they reunited because "they have nothing else to do, nothing else is happening in their lives".
"One's just a wife of a footballer and the others are not on the radar. They're well past their sell-by dates," he said.
