The final 24 jet off to various places across the globe and sing to win a place on the live shows for their judge, either Gary Barlow, Louis Walsh, Nicole Scherzinger or Sharon Osbourne.
The groups and Gary are heading to New York, and he's joined by X Factor alumni Olly Murs, meanwhile Sharon and the over 25s head to Los Angeles, and Robbie Williams is on hand to help her choose her final three.
Nicole and her guest judge Mary J Blige head to Antigua with the girls. And finally Louis takes a trip to San Tropez, with no less than three helpers: Nicole Appleton, Shane Filan and Sinitta.
Who will see their dreams turned into reality and make it through to the lives?
The X Factor, ITV, 8pm
