The X Factor group 4th Impact channelled their inner Beyoncé for a fiery performance of ‘Work It Out’ . And it was just moments after Celina had passed out backstage (Nov14).

The Filipino sisters mentor Cheryl Fernandez-Versini revealed before the girls’ performance that Celina had been treated in an ambulance but that the sisters had refused to pull out of their performance.

The judges gave a standing ovation.

“I’ll make this very quick because of what you’ve been through – I was backstage when all this happened,” Simon Cowell told them.

“All I’m going to tell you is that I’ve done this a lot of years and  that was, under the circumstances, one of the most incredible things we’ve seen on this show. It was unbelievable… After today and what’s happened to you lot it was outstandingly good. And I hope you’re okay, sweetheart.”

And the girls’ mentor Cheryl Fernandez-Versini said she was “so proud” of them all, saying that they vowed to perform even though they could have used the dress rehearsal tapes.

“That’s what stars do,” she said. “We have sore throats or you lose your voice and you have to just do it, and you girls brought that tonight without having professional experience.”
