Ella Henderson has promised to shock on The X Factor 2012 tonight with her song choice.
This evening will see the remaining six acts taking on those songs that they hate to admit they love, as the finalists perform their guilty pleasures.
The teenager has wowed with various covers over the past seven weeks, singing songs including Katy Perry's Firework and Cher's Believe.
Speaking about her song choice this weekend, Ella said: "It is guilty pleasures week. I found the theme really hard this week but I've taken it on as a challenge - I'm really excited."
She explained: "I'm going to do a song that everyone's just going be so shocked and going to think, 'What the hell is she going to do with that?' But I'm really excited about it all."
Speaking at the premiere of the new Twlight movie, Ella continued: "I guess there's only four weeks left of the competition - it is kind of appearing in everybody's minds now and you do want to get to the end but I'm just going to enjoy it now because, what have you got to lose?
"I've made it this far so I'm just going to enjoy it and just see where it goes and whatever happens will happen. That's how I'm looking at it."
Meanwhile, the schoolgirl gushed about her mentor Tulisa.
"Tulisa's wicked as a mentor, we're like chalk and cheese but we get along so well, she's like a big sister," Ella added.
