Tonight we get to see the final 12 perform live on The X Factor. Simon's three boys (Eoghan Quigg, Scott Bruton and Austin Drage) are up against Cheryl's three girls (Alexandra Burke, Diana Vickers and Laura White). All six youngsters are also competing against Dannii's over-25s (Rachel Hylton, Daniel Evans and Ruth Lorenzo) and Louis's bands (Bad Lashes, Girlband and JLS). It's early days yet, but I want some predictions people! So tell me: which category contains this year's winner?
