X Factor 2012 favourite Ella Henderson has been struggling in rehearsals this week with an ear infection.
The teenager wowed the judges with her cover of Take That's Rule The World last Saturday night, and faces an tough challenge to try and match it this weekend.
Gary Barlow said after last weekend's performance: "There is nothing I hate more that someone singing my song ten times better than me!
“That was stunning! To feel the way you do is absolutely extraordinary.”
16-year-old Ella however has been pushing on, hard at work in rehearsals.
She tweeted today: "Morning xx this weeks going too fast! Thursday already! Ahhh"
And the singer, who wowed with her own track in her first audition, added: "Rehearsal time !!! Xx and it all begins again ,... Ahhhh #yayayaya"
Ella is the favourite to win, but vowed this month not to let the pressure get to her.
“I will be nervous before the live show but I don’t feel pressured," Ella said. "I’m just excited to think I’m still so young and I’m going to be able to keep pushing myself.
“I’m bound to go wrong at some point like everyone else – I’m not perfect. I’m going to be me and give the most honest performances I can.”
She added: “I’ve had words with Tulisa about keeping my feet on the ground and I know I can go to her at any point if I feel it’s all getting too much.”
Speaking to The Sun, Ella revealed how living with the other finalists was making her feel like she was in the Big Brother house!
She said: “It feels like the Big Brother house at the moment. We have had one or two funny nights. There are quite a lot of boys so the testosterone is flying around and there’s lots of shouting.”
The X Factor 2012 continues this Saturday night on ITV1, with the results show following on Sunday night with performances from Taylor Swift and Rebecca Ferguson.
