There's only one question on everyone's mind - Who has the X Factor? Only three acts from each category now remain: Kate Ceberano with the 16-24's year olds, John Reid with the 25 and overs and Mark Holden with his vocal groups. Watch them perform live in front of a studio audience and the nation! Who will welcome the spotlight and who will crumble? So... do you know who has the X Factor?
