Girl group IV Rox wowed the X Factor 2014 judges at their arena audition this weekend.
The four piece made up of Raquel, Natalie, Dolly and Nadine had quit the rough ride at their room audition.
They "crumbled and cried" after Simon Cowell stopped their song.
But despite being left "so upset", they still managed to scrape through to the Wembley round.
"What you should have done is taken a song we've never heard before and made it your verson to show us you're smart," Simon told them.
Cheryl warned: "[At Wembley] You've got to bring your A game."
Speaking ahead of their performance in front of 5,000 X Factor fans at Wembley, the group said: "Some of our favorite acts have come from this show, we've watched them and we feel like we have the potential to be something great."
At their audition, IX Rox performed their own spin Case Of The Ex by MYA.
"What an improvement!" Mel exclaimed.
Simon told them: "I think the good thing is you guys took my voice, it is a massive, massive improvement."
