Girl group Little Mix are known for looking amazing all the time, but the stars have revealed that they have their own 'beauty sins' that they're sometimes guilty of. 

During an interview with Superdrug's DARE magazine, the 'Black Magic' sensations explained that they aren't perfect and sometimes make bad choices where their cosmetics routines are concerned.

Perrie Edwards explained that the worst thing she does is go to bed with her make-up on: "Sleeping with my make-up on! I'm not as bad as I used to be, but it's quite gross and so bad for your skin." Member Jesy Nelson added: "Not taking my make-up off when I've had it done the day before by my make-up artists. That's so bad!"

The girls were then asked how they like to unwind when they get time off and Edwards said she enjoys getting pampered: "During my time off, I love to get pampered. I also love to relax and watch TV. I'm all about the chilling." Leigh-Anne Pinnock added: "I love to party. I absolutely love getting my glad rags on and partying the night away with my girls. I also love those girly nights in with nachos and hot chocolate."
