The theme is 'Get Me To The Final', and Simon Cowell has no acts left to help through, while Rita Ora is the only judge with two girls still in it.
Hot favourite Louisa Johnson is going to be belting out 'It's A Man's Man's World', and 'The Power Of Love', and Lauren Murray will perform 'Runnin'' and 'Best Of My Love'.
Nick Grimshaw's final act Che Chesterman is doing 'Would I Lie To You?' and 'Love Is A Losing Game', and Cheryl Fernandez-Versini's group, Reggie 'N' Bollie, will sing 'Locked Away' and 'I Like To Move It'.
Who will Caroline Flack and Olly Murs be congratulating and who will they be commiserating with as they fall at the final hurdle?
