Though Glastonbury Festival‘s full 2016 lineup has yet to be revealed, Adele said “Hello” to the popular U.K. event on her own terms, announcing Friday to a packed house at London’s O2 Arena that she would headline this year’s Saturday night performances.

Shortly after the announcement, made on stage as part of her Adele Live 2016 arena tour, Glastonbury’s official Twitter account confirmed the news:

Previously announced acts include Muse, who will headline the festival’s Friday night, while Coldplay will close the event two days later on Sunday evening.

The 2016 Glastonbury Festival will take place June 22–26 at Worthy Farm in the U.K.
