Speculation around The Cure headlining the festival has been rife since the band announced a run of European festival appearances earlier this year, plus a series of dates to celebrate the 30th anniversary of seminal 1989 album Disintegration.
The Cure haven't performed at Glastonbury since 1995 and their booking means they'll equal a record now held by Coldplay, becoming the only band to have headlined the even four times.
The band previously performed at the event as headliners in 1986, 1990 and 1995.

Stormzy will perform Friday night, The Killers will take Saturday, and The Cure's locked in for Sunday.
Festival organiser Emily Eavis, who curates the line-up with her father Michael Eavis, said previously: 'The gender balance is something I consider at every stage of the booking process. We're definitely moving in the right direction'. The festival plans to announce more artists ahead of its kick off the last week of June.
