Now that the final 16 X Factor contestants have made it through auditions, bootcamp and the judges' houses, it's time for the really exciting part to start - live shows. And with live shows comes one of our X Factor highlights (other than Robbie Williams and Gary Barlow joining forces, of course) - the unveiling of the finalists' all-new pop star make-overs.

And when the images of the newly made-over final 16 landed in our inboxes, we couldn't help but notice that they were dead ringers for other stars. So, we've dug through the A-list photo album to bring you a fun look at each of the finalists' celebrity look-a-likes...
