Adele dropped the bombshell last night at a show at London's O2 Arena, reportedly telling the crowd: "I wanted to do it last year but my record wasn't ready. And to the people who say I am too boring to headline, you're more fucking boring for moaning about me headlining."

Glasto organiser Emily Eavis has been coy about Adele's booking; recently, when it was suggested that Adele would be a good headliner, Eavis said: "She would, wouldn’t she? It would be great to get her."

Adele herself said it was unlikely she'd ever top the Pyramid Stage last November, telling Capital London radio: “I think I have made myself pretty clear on Glastonbury… The crowds are too big - I don’t know if I could do it.”

The record-breaking singer joins fellow headliners Muse and Coldplay, as well as PJ Harvey, Jeff Lynne's ELO, and Grimes at the Worthy Farm event.

Glastonbury 2016 takes place 22-26 June, and is sold out.

As @Adele just announced live on stage in London, she will headline Saturday night at this year's Glastonbury Festival!
