The group - made up of Charlie, 17, Parisa, 20, Mikey, 19, and Betsy Blue 18 - impressed mentor Louis Walsh and returning X Factor star Tulisa with their rendition of Ella Henderson's 'Ghost' while at Judges' Houses in Bermuda.
With Louis picking them as one of his final three groups, Only The Young are preparing for their first live show performance and have joined their fellow finalists in the X Factor's plush pad in London.
Having lived together in Parisa's family home, Only The Young are no strangers to being housemates and appearing on Good Morning Britain earlier today, the group revealed how they have been getting on in the X Factor house.
Betsy told Ben Shepherd and Susanna Reid "everyone in the house is so much fun" while Mikey said he thought Cheryl Fernandez-Versini's finalist Chloe Jasmine was "funny" and "great to chill out with".
Revealing everyone in the house is already settling into their roles, Parisa said: "Jake Quickenden is like a big brother to everyone, Jay James gives advice… it's a really nice vibe in the house."
Before all moving in, Only The Young revealed they had already been briefed on how much their lives are going to change now they are heading into the lives show.
Having already had a taste of fans and paparazzi waiting outside the house, Charlie said: "It's really scary... it's a weird experience."
Only The Young will join Louis' other two groups - Blonde Electra and New Boy Band (yet to be named) - as well as Simon Cowell's overs, Cheryl's girls and Mel B's boys in this weekend's (11 October) first live show.
