Jade Thirlwall, Leigh-Anne Pinnock, Perrie Edwards and Jesy Nelson co-wrote the song for an upcoming album, but decided it wasn't quite their style - and so the track was offered to Spears, who loved it and invited Azalea to join her in the studio.

The Toxic singer and the rapper debuted the song onstage at the Billboard Music Awards in Las Vegas earlier this month (May15), and now Little Mix have given the track their own spin during an appearance on London radio station Capital FM.
