We don't know on which song and how she will be featured BUT we will find out Dec. 4th
Quote:
The album, recorded in Malibu, LA and London, was produced by Norwegian duo Stargate together with the band’s long-time collaborator Rik Simpson. It features more guests than any previous Coldplay record, with Beyoncé, Noel Gallagher, Tove Lo and Merry Clayton among those appearing across its 11 tracks (12 if you count the buried treasure of the hidden track X Marks The Spot).
