Simon Cowell has reportedly picked a track already performed by finalist Joe McElderry as this year's winner's song.
The X Factor judge is said to have chosen Journey's 1981 hit "Don't Stop Believin'" as the winning act's single - a song which Joe performed during Rock Week.
His decision has led to speculation that he believes the 18-year-old will triumph in the final, reports The Sun.
The second choice for the winner's song is "The Climb" from the Hannah Montana movie, which is being considered if it looks like Stacey Solomon may beat Joe in the final.
A source told the paper: "It is getting to the crucial stages now and Simon and the producers are very confident that Joe could be the winner. He made a great fist of "Don't Stop Believin'" and that has helped.
"It's always a difficult call choosing the song, especially as there are some very different talents in the final line-up."
They added: "Danyl and Olly really think they can win. They will be shocked to learn the winner's song is one Joe has already performed.
I'll be DEAD if they release "The Climb" considering that it was never a big hit in the UK and it'll go No. 1. But that may cause Miley's version to get a new peak.
EDIT: I don't watch this since they kicked Jedward out.
