The Take That star allegedly wants his last remaining act to perform with Wonder in the event that he reaches the show's final, an idea sparked by Collin's well-received performance of 'Lately' this weekend.

"Marcus has the whole of Liverpool voting to get him through to the final, but Gary thinks Stevie Wonder would give him a real push in the final to get the whole country spurring him on to victory," a source told The Mirror.
"Gary is trying to use all his contacts in the business to make it happen. Bosses would love a music legend like Stevie on the show, too, and would get him to do a medley of his hits at the same time."
Michael Bublé and Jessie J have also been tipped to perform with contestants on The X Factor final.
Coldplay recently confirmed rumours that they had been approached for an X Factor appearance, though frontman Chris Martin said that the band were split on whether to accept the offer.
