Skarl3t are aged 22-27 and made up of Tonia, Naomi and Natasha.
After taking on the wall of songs twist they end up in a group with Kayleigh Marie Morgan and Tinuke, another act cut from the auditions, singing Marvin Gaye 's Ain’t No Mountain High Enough.
But there are disagreements over who will sing what parts and it leads to Skarl3t going to rehearse away from the group.
Kayleigh tells cameras: "Bootcamp is such a daunting place, there's probably more talented people here than there is actually people in my village.
"At bootcamp, my biggest fear is I'm going to be pushed aside. Because you do have to work in a group, sometimes it's really hard to get that limelight... I can't even explain how much it literally means to me."
With the three acts not working together, Kayleigh admits: "It's making me feel really uneasy."
But Skarl3t declare: "This is a competition. You can be cool with everyone but you're not here to make best friends, it's not camp."
After the three acts perform for the judges, Nicole Scherzinger admits she's "really disappointed" as the panel discuss the trio of acts.
Simon Cowell remarks to the group: "I could tell there were issues on the rehearsals of that song. That song is one of the greatest pop songs ever written and when you're given it, you've got to treat it properly... So who's to blame?"
Tune in to see the performance and to find out which acts make it through to the six chair challenge on this evening's show.
