The X Factor 2012 semi-finalists are set to perform with Rod Stewart this weekend, it's been claimed.
Producers have managed to convince the singer to perform with Union J, James Arthur, Jahmene Douglas and Christopher Maloney on Sunday night's show.

“It is a big coup to get Rod — and to get him to perform with the contestants," a source told the newspaper.
They added: “He is an absolute legend and is a big fan of the show.
"He jumped at the chance of being able to perform.”
The X Factor 2012 continues this weekend on ITV1 and ITV1HD with the final four acts singing songs that they hope will get them into the final.
