They have made X Factor history by becoming the first girlband in the history of the show to reach the semi-finals.
But it seems the pressure might be getting slightly too much for Little Mix, who have revealed they are struggling to cope in the spotlight.
The girls told Look magazine they have been working so hard to continue in the competition that it has left them feeling more than a little tired.

Asked if they were trying not to be sexy in a bid to get younger fans to relate to them, Perry replied: 'It's not deliberate. We just can't be sexy!'
Jade added: I'm like a toothpick. I can't be sexy at all. A few boys on Twitter have said what's sexy is that we're trying not to be.

And talking of being a good role model, Jesy said in the interview she has been overwhelmed by the support she has received from fans after revealing her struggles with her weight.
She said: 'I got comments about my weight when I was younger too but I'd never go on a diet - this is how I am and these girls have taught me to embrace it.
'We're all different and I like being me.
'The nicest thing has been getting messages from girls who are being bullied, who say that now they don't feel alone.
'One girl said that seeing me go on stage and be happy has inspired her.'
Little Mix have even won themselves an army of celebrity fans, with David Walliams and Lara Stone supporting the group live on the show.
Daisy Lowe tweeted her support for the band, writing: 'Ahhhhh my love for Little Mix is getting overwhelming,' while Pixie Geldof was photographed with the girls at a recent party.
