Abi Garrido, 17, Abby Eades, 18, Leah Gooden, 16, Mimi O'Connell, 17, and Saffron Silva, 17, entered the competition as soloists but were put into a group by the judges during Bootcamp.
"There's no words to describe how it feels," they said. "Mad, surreal, so much excitement. Anything can happen here."
The girls make a rather interesting group too! Abi is continuing the family tradition of performing, as her mum, grandma and granddad were all singers, while the other Abby is a Cheryl impersonator in a Girls Aloud tribute act!
Leah actually lived in France for six years and speaks fluent French, while Saffron sings every week at Westfield shopping centre. The X Factor opportunity is also precious for Mimi, who has a severe heart condition and first performed at a summer camp for sick children in 2010.
For the girls, having Tulisa as a guest judge in Bermuda was good news: "She understands things from a girl's point of view, and she mentored Little Mix."
Will the girls be able to impress Louis and Tulisa for that coveted place in the live shows?
"We know it's a competition, but if we start thinking that way it might get to us," they said. "We're all in the same boat so it makes sense to help each other."
