'X Factor' Guilty Pleasures & Heroes quarter-final - In Pictures

X Factor's Final 5 took to the stage twice tonight to perform one track by their 'Heroes' and one personal 'Guilty Pleasure'.

Janet Devlin, Amelia Lily, Misha Bryan, Marcus Collins and Little Mix are all just two rounds away from The X Factor final, so the pressure was really on when they took to the stage at Fountain Studios.

As tension increases between the acts, the in-fighting between judges Gary Barlow, Tulisa Contostavlos, Kelly Rowland and Louis Walsh inevitably went up a notch as well.

If the acts can survive the chop in tomorrow's elimination, they will be one show away from a spot at X Factor's biggest ever final at Wembley Arena.
