4th Impact's Celina collapsed on stage after the girl group were eliminated from 'The X Factor' on Sunday (29.11.15).
Celina, 19, who performs in the group alongside her sisters, Mylene, 23, Irene, 25 and Almira, 27, suddenly passed out after the cameras stopped rolling, while they were chatting to mentor Cheryl Fernandez-Versini.
A source told the Daily Mirror newspaper: "Everyone was saying their goodbyes to the girls and then suddenly Celina hit the floor.
"Her sisters were shocked and Cheryl started calling for people to help.
"Two men ran on stage and carried Celina backstage, she looked lifeless. Celina was out cold for at least five minutes. An ambulance was called and she was treated onsite."
The group later took to Twitter to assure fans that Celina was fine, writing: "Thanks to all who voted for us why we reach this far. Celina is ok now thanks for your prayers and love (sic)."
4th Impact were voted off the show after losing the sing-off to Lauren Murray.
Just two weeks ago the group almost missed performing on the 'X Factor' after Celina passed out during rehearsals.
However, she recovered to perform 'Work It Out' by Beyonce Knowles with her sisters.
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."
