The chart topping British girl group (pictured) will star in a new TV advert for the female sports brand, which is due to air in January, and work with USA Pro on their own collaboration, which is due to be released in summer 2016.
Rebekah Walker, USA Pro brand manager, says: “2016 is going to be a huge year for USA Pro and we’re delighted that Little Mix will be at the forefront of our #JoinOurMovement campaign.
“They’re all young, beautiful and stylish, but like all girls they have their own personalities, tastes and body shapes.
“Those values of individuality and inclusivity fit perfectly with USA Pro.
“We’re really proud to have them as global ambassadors.”
