The "Paradise" singers, who were hot favourites for a headline slot, have announced their set by posting a picture on Twitter of the metal structure of the iconic Pyramid stage in a field filled with sheep.
In the snap, a wooden post features the artwork for Coldplay's A Head Full of Dreams Tour and the date "Sunday, June 26", the last night of the festival, which runs between June 24 and 26.
The announcement on the band's official website reads, "Coldplay today became the first headline act to be confirmed for Glastonbury Festival 2016. They will top the Pyramid Stage bill on Sunday, June 26th.
