Producers are trying to get the 'Hung Up' singer on an upcoming Sunday night results show in a bid to attract record ratings, the Daily Star Sunday reports.
'Getting Madge on to sing is bound to pull in the viewers. You don't get much bigger than her - she's a living legend,' a source told the paper.
'The show has regularly been getting ratings of over ten million. Having Madonna, plus the all-important results, could push it past the 12 million mark.'
'X Factor's finest hour was getting Britney Spears on - but there's no doubt Madonna is a much bigger name. Simon Cowell will be furious if The Voice upstages him with a massive guest performer like Madonna in its first series.'
