Madonna 'Snubbed The X Factor Final'
Queen of pop reportedly refused Simon Cowell an audience...
The pop icon has been a target of SiCo's for months, but The Sun reports that she has resisted his overtures to sing at the series finale.
The current guest line-up includes One Direction, Ed Sheeran and Sam Smith - but the paper claims producers were also hoping to land a bona fide megastar.
A source told the paper: "There are very few people in the music world who Simon can't appeal to. He has made no secret of the fact that he is desperate to get Madonna on board but she just won't do it.
"The X Factor final is one of the biggest shows on the planet and a great platform for anyone who wants to sell records. It is a big blow to the final.
"They have already got some absolutely brilliant names in One Direction, Sam Smith and Ed Sheeran. They are three of the biggest stars of the moment but none of them has that real wow factor - and One Direction are already so closely associated with The X Factor.
"A huge American star such as Beyoncé, Christina Aguilera or Rihanna makes people's jaws drop to the floor."
