The three remaining girls in the X Factor, Misha B, Janet Devlin and Amelia Lily, who made a big return to the show last week, have revealed to MTV News what they have in store for tonight's performance.

16-year-old Amelia retains a level of mystery to what she will be doing tonight but cites that it will be fun:

"It’s going to be fun, that’s all I’m saying. It’s going to be fun".

Irish singer, Devlin's performance was criticised by the judges last week but she promises to hold on to her own style whilst doing an upbeat number:

"This week, I’ve taken a really romantic song and just made it my own, you know I’ve made it more up tempo".

The 17-year-old also added that the competition is getting harder and no one knows who will go next:

"The competition is always getting tougher, it’s been tough from the start. Now it’s just worse because whoever goes is going to be a shock , no matter what. That’s the worst part I think".

Misha B was placed in the bottom two last week and she says that that will add fire to her performance:

"Well, you know you take one knock and you still get back up fighting so for me, this is me being me, and showing what’s really going on inside".

The X Factor is on ITV1 tonight at 8.15pm.
