Little Mix have indulged in their raunchy side for an amusing Instagram video.

The girl group, who are currently in the States supporting Demi Lovato on tour, uploaded a video of themselves performing the "sexiest dance" ever on bandmate Perrie Edwards.

Whilst Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall put their all into thrusting their bits and bobs in front of Edwards, she barely flinched.

The clip ends with the three singers all seductively dancing around their blonde bandmate, who continues to message on her phone.

Up next on the Neon Lights tour meanwhile is a date in Grand Prairie, Texas tonight (February 17).

Fellow Brit Cher Lloyd and Fifth Harmony are also providing support on the run.
