BOOTED-out X Factor singer Stacey Solomon may have had her victory chances scuppered by MADONNA.
The superstar, 51, had been in talks with Simon Cowell to appear in Saturday's final, with insiders claiming she was set to duet with Stacey.
But the deal collapsed and the snub is being blamed for Stacey losing after she sang with Canadian crooner Michael Bubl� instead.
A show source said Madge's team would only let her perform if she had an album or tour to plug.
The source said: "We were told she wasn't in promotion so it wasn't going to happen.
hey wait a second what about revolver?? lol
"It's a shame as she'd have been brilliant and given the show a real lift, especially with Stacey."
Fans of Stacey feel that Bubl� does not have the same popular appeal as Robbie Williams, who partnered Olly Murs, and George Michael, who did a duet with Joe McElderry.
Some are so furious that they have urged Brits to boycott the winner's song.
