THIS is it then. The not-so-dirty dozen who will go through to the next, all-important stage of the contest will be decided this weekend, so there's no shortage of tension behind the scenes.
As ever, judge Louis Walsh will be offering his words of advice, while potentially comparing the acts to 'younger' versions of well-known pop stars.
Meanwhile, the slightly mellower (or is it just us) Simon Cowell will be giving his verdict on the acts, along with Cheryl Fernandez-Versini, and one of Leeds' loudest exports, Mel B.
The X Factor will be on ITV1 and ITV1 HD from 8pm.
