Spiky-haired twins John and Edward Grimes fear they might have blown their X Factor chances after a performance of the Backstreet Boys' I Want It That Way.
This weekend's episodes see the 24 remaining acts visiting the judges in exotic locations across the world, to impress their mentors with their singing talents once again.
Dannii Minogue is joined by her big sister Kylie, to help her choose which acts to take through to the next round.
Meanwhile, Simon Cowell's helper is singer Sinitta, who dons a daring outfit made up of some well-placed palm leaves.
Mentor Louis Walsh has championed the twins, despite them coming in for ridicule from several quarters.
But following their performance, the normally confident 17-year-olds are seen crying.
Edward says: "I just feel like we go home and then it's just like 'What the hell, that's it', then that's what we're remembered for, that's the end, no."
John adds: "Yeah, like on a bad note, unbelievable bad note."
Edward agrees: "Yeah, I think we meant our best. It could have gone well and it didn't."
Meanwhile, Kylie is impressed by Stacey Solomon's version of the classic ballad Over The Rainbow.
Kylie says: "I sung that song every night on tour for a while and it's one you don't want to mess up but for me it was flawless."
The X Factor will air on UTV at 8pm and the 12 remaining finalists will be announced on Sunday night, in a programme which goes out from 8pm.
