Celina, the youngest of the four siblings at just 19, passed out during rehearsals and it was thought the band may have to miss the live show this evening (14.11.15) but they defied odds to perform 'Work It Out' by Beyonce.

After their performance, Simon Cowell said: "All I am going to tell you is, I have done this a lot of years. That was, under the circumstances, one of the most incredible things we have seen on this show. It was outstandingly good."

Whilst Nick Grimshaw added: "Girls, it was outstanding. Beyonce is a perfectionist and that was perfect, it really was. You seem a lot more grown up tonight."

Rita Ora praised Mylene, 23, Irene, 25, Almira, 27 and Celina for their "really inspiring performance".

She shared: "That was for me a really inspiring performance. You see so much hunger in your eyes. You breath this. It got to show."

Their judge Cheryl Fernandez-Versini told them: "I am so proud of all four of you girls to get up there tonight under those circumstances. You had the option to use the dress run takes, but you said absolutely not."

Elsewhere on the show, Che Chesterman earned a standing ovation for 'When A Man Loves A Woman' and Louisa Johnson performed a powerful rendition of 'Everybody's Free'.

The 'X Factor' continues tomorrow (15.11.15).
