They may only be in their teens but the X Factor girls have transformed into young women since being on the show.
Janet Devlin and Amelia Lily Oliver have secured their place in this week's quarter final along with fellow contestant Misha B but their time before and during the show hasn't always been so glamorous.
Speaking to NOW magazine, the trio revealed what really goes on behind the scenes and how they feel about the once in a lifetime opportunity.
Lucky to be back: Amelia Lily revealed that she never thought 'in a million years' that she would return to the show
'It’s absolutely incredible, Never in a million years did I think I’d be coming back,' she said. 'The X Factor’s the hardest thing I’ve done in my life, but also the best.'
Wearing an all black outfit that consisted of a corset, bow tie and black star-print tights, the pink-haired singer also revealed that it was her illness that had made her so strong.
'I was diagnosed with Chronic type one diabetes when I was three so I’ve grown up having four injections a day, she said.
Where's you hair gone? Janet Devlin wore a sequined corset and black shorts as she insisted that she is no push over
The former dance school pupil also shed light on her relationship with controversial contestant, Frankie, by saying: 'We’re just friends. Frankie’s like a brother to me.'
Janet was also adamant about backstage details of the ITV show, stating that she is in charge when it comes to her performances.
'I won’t do what I don’t want to do. I won’t do anything that isn’t me,' she said.
'Misunderstood': Misha B revealed that her life could have gone a very different way due to her troubled childhood
Wearing a multi-coloured sequin corset with black high-waisted shorts and a blazer, the red-head looked every inch the pop star but there was a time when the teen's look was a problem.
'At school I had a problem making friends and it was tough,' she revealed. 'I wasn’t cool – I had very long blonde frizzy hair, I never wore makeup and I wasn’t pretty.
'People would take the mick out of me. I don’t like talking about being bullied, but I forgave the girls who did it. Since then I’ve just had a small circle of friends I feel comfortable with.'
Someone who found themselves at the opposite end of the scale was 19-year-old Misha B.

'After I walked off, my phone started going and all these texts and tweets bombarded me, half of them saying "what just happened?" and the other half saying I was the most horrible person. It was awful.'
Wearing a black corset dress complete with a feather skirt and a red sequin collar, Misha went on to explain how her life could have turned out totally differently.
'I was misunderstood and a troubled kid because of what I went through, she said.
'I’ve been amazingly lucky to have my aunt Lily - who I call mum - because she’s always been there for me, but my teachers didn’t understand me. At the age of 16 I could’ve gone a very different way and achieved nothing.'
The Manchester hopeful went on to say that her celebrity following is growing with Nicole Scherzinger, Tinchy Stryder, Perez Hilton, Rio Ferdinand, Cee Lo Green and Chipmunk all telling her that they are fans of hers.
The three hopefuls will join their fellow contestants, Marcus Collins and girl group Little Mix, to sing two songs each in this Saturday's quarter final.
