Little Mix - also formed of Perrie Edwards, Jade Thirwall and Jesy Nelson - have been spending some quiet time after a busy few months on the road.

Discussing their upcoming fourth album, Jade recently told MailOnline: 'It's moving a lot faster than any of the other albums have done, because we want to release it before Christmas, which means we have to have the first single ready pretty soon.'

Five years on from their first big break, and the girls haven't stopped recording, performing or working for more than a few months.

And it seems that album number four started while they were hard at work on their globe-trotting Get Weird tour.

'We've been setting up writing camps with people we know, so even we if can't make it to a writing session the music is still sure to be relateable to us,' said Jade.

Not long to wait: The girls recently revealed their fourth album could be out before Christmas
