Little Mix has unveiled their second sportswear collection with US Pro, and it's full of bright colours and flattering silhouettes.

The inspiration behind the new range is functional but fashionable gymwear. It includes 11 items - from sports bras to leggings, tops and sweaters - with pieces reflecting each of the girls' unique styles.

Of the new line, Perrie, 24, says: “For our latest USA Pro collection I wanted to add a modern twist by using cool abstract prints and simple silhouettes to accentuate a woman's natural body shape”.

25-year-old Leigh-anne added: "I've created a range to suit every shape and figure with bold panels of neon against a solid black fabric."

Yesterday, whilst doing an interview on Spanish radio station LOSO4, the girls revealed they will be releasing a new single, in time for the festive season.

Jesy said: "We'll be releasing a new single before we go on a Christmas vacation." No more, no less. Exciting though, right?"

As well as launching the second USA Pro collection the girls also revealed their personal health and fitness tips.

Jesy, 26, says that working out together is the ultimate fitness regime, saying: "When Little Mix are in rehearsal for a tour we're working on the routines every day for two or three weeks. Then, once we're on the road, it's an hour and half of dancing every night. When keeping fit is fun it's so much easier."

Perrie, who is dating footballer Alex Oxlade Chamberlain, confessed that she sometimes struggles to eat healthily but revealed that working out with other members of the group gives her extra motivation: 'The girls egg me on because I'm not as fit as some of them, so having three fantastic fitness buddies is an added incentive.'

But 24-year-old Jade takes a DIY approach to keeping fit when she's busy, saying: "You can't always find time for the gym but if you managed to squeeze in a few sit ups and squats every day at home you don't feel so guilty."
