If you thought The X Factor or I'm A Celebrity...Get Me Out Of Here were the biggest competitions this year, then you were wrong!
The biggest battle of 2015 comes down to your choice of headwear, and the question Little Mix are asking is this: Are you a beanie or a bobble wearer?
The girls haven't got all passionate about knitted hats for no good reason though, the 'Black Magic' hitmakers are the new faces of Matalan's new Christmas campaign, Beanie vs Bobble, in support of Alder Hey Children's Hospital Charity.
To support the campaign, Jesy, Perrie Leigh-Anne and Jade will also give an exclusive performance for the patients and staff at the new state of the art hospital.
Jason Hargreaves, Managing Director at Matalan, said: "We're extremely excited to be working with Little Mix on such a special project this Christmas, creating awareness that will help raise funds to continue important research at the new hospital, whilst also offering the perfect gift for Christmas."
It's not just about Little Mix though, sorry girls, Matalan are encouraging the rest of us to choose a Beanie or Bobble side, grab a hat (kids £4, adults £8) and get our selfie on.
Here are the girls taking their very own selfie, if anyone's after some inspiration...
100% of the profits raised by the campaign will go towards Alder Hey's new research, education and innovation centre. And we'll get to be all toasty and warm over winter!
