Viwers will tonight see X Factor bad girl Chloe Mafia's hangover horror show as she is late for boot camp practice.
The dancer, 19, is shown getting off to a bad start as 200 acts are slashed to just 32 in this weekend's two shows.
She says: "Like a stupid idiot I went out last night and I haven't been to sleep yet. I feel sick and can taste vodka in my mouth.
"I've got the same make up on I've had since yesterday morning. I just look disgusting."
Also hoping for no slip-ups in front of Simon Cowell, Louis Walsh and guest judge Nicole Scherzinger is Cher Lloyd.
Insiders have suggested stress is taking its toll on the 17-year-old frontrunner. And Dublin check-out girl Mary Byrne, 50, almost blows her chances after a boot-camp breakdown.
She runs off stage in tears, to be comforted by host Dermot O'Leary, after messing up. But Louis convinces Cowell to give her another chance.
The contestants are split into Boys, Girls, Over-28s and Groups, with each category being allocated a song to sing.
Cowell explained: "If you've got a lot of people and you've got limited time, this is the most brutal and effective way of just seeing who the deadwood is and who has got a bit of something different."
