Contestants can't wait for special 'duet'...

You read it here first - the official X Factor website can exclusively reveal that special guest star Mariah Carey will sing number one single Hero live on stage with the X Factor finalists tomorrow.

This historic performance will give The X Factor Finalists' version of Mariah's original 1993 hit her official seal of approval - in a spectacular way.

There is no doubt that this will become one of the real must-see moments on British TV.

Thanks to the fabulous generosity of you guys out there, Hero is still number one in the charts as Remembrance Sunday approaches.

And Mariah will add her voice in support of the single which donates all funds to the joint causes Help for Heroes and The British Legion Poppy Appeal. Both charities support injured British troops.

The pressure is on for the contestants who, as well as singing alongside Mariah in this unmissable one-off collaboration, will each choose a track from Mariah's Songbook to perform on the night.

Mariah herself will perform twice. As well as singing alongside the contestants on Hero, she will perform her newest release, the single I Stay in Love.
