Tickets for the festival have already sold out.
Singer-songwriter Ed Sheeran is to headline the Pyramid Stage at this year's Glastonbury Festival.
He tops the bill alongside Radiohead and Foo Fighters, who previously cancelled due to an injury sustained by snger Dave Grohl.
The chart-dominating pop star will close the event on Sunday, June 25th, in his only scheduled festival appearance this year.
In a short Instagram film, he described the news as "awesome", ending speculation about 2017's headliners.
Sheeran first played Glastonbury in 2011, appearing on the BBC Introducing stage before his debut album - +, or Plus - had been released.
He returns to Worthy Farm as one of the world's biggest pop stars, having sold four million copies of his third album, Divide, in the last 10 days.
The star also dominates the singles chart, with all 16 of the tracks on his album residing in the Top 20.
Radiohead are the Friday night headliners, making their first UK festival appearance since 2011, with Foo Fighters heading up the Saturday night slot.
The full festival bill is due to be announced in early April, once fans have paid the remaining balance on their tickets.
Organisers recently revealed that "twice as many bands" had been booked for this year's event, which runs from June 21st to 25th at Worthy Farm in Somerset.
