The video for the X Factor winner's single will reportedly be based on the a Baz Luhrmann-directed Chanel perfume advert featuring Nicole Kidman.
According to The Sun, the promo clips have already been recorded for the three remaining finalists Olly Murs, Stacey Solomon and Joe McElderry.
A source said: "Simon is going for a lavishly-produced video to give the song a massive boost.
"All three acts gave a great turn, so whoever wins it'll be a cracking video."
The videos reportedly feature the singers dancing in puddles while singing a cover of Miley Cyrus's 'The Climb' in front of a London skyline.
The X Factor final airs this Saturday and Sunday evening on ITV1.
