Rumours Madonna, Dua Lipa and Coldplay will headline Glastonbury next year are "untrue", according to the festival's organiser.
On Saturday evening, the Mail on Sunday reported the three acts were set to top the bill on the Pyramid Stage in June.
But Glastonbury co-organiser Emily Eavis said the story was not correct.
She wrote on Instagram on Sunday morning: "As always, there is much speculation and excitement about who is playing at Glastonbury.
"We are working on the line-up day and night at the moment, but it's still changing every day.
"The story about our confirmed headliners is untrue.
"As always, we love your enthusiasm and guesswork - but accurate news on headliners will be with you sometime in the new year!"

The report said Dua Lipa would headline on Friday while Coldplay - who have headlined four times previously - would take the Saturday slot.
Madonna would close out the festival on Sunday, the newspaper said.
If true, it would have been the first time two female artists have featured in the premier spot.
The festival was criticised for having all-male headliners last year with Arctic Monkeys, Guns N' Roses and Sir Elton John.
Next year's festival at Worthy Farm in Somerset will take place from 26 to 30 June.
Last month Ms Eavis told Annie Mac and Nick Grimshaw's Sidetracked podcast the legend slot on Sunday afternoon would be a female artist.
Addressing last year's lack of female headliners, Ms Eavis added: "I've always been really passionate about gender split [on festival line-ups] and I think, actually, our problem was that I'd been so outspoken about it that having a year when there wasn't a female sent people a bit mad - or some people.
"And we did have a female - she pulled out and we replaced them with Guns N' Roses. But everyone knows that it's top of my list.
"It is difficult with female artists because there aren't enough headliners. But we're also creating them.
"We're putting the bands and female artists on smaller stages and bringing them through all the time. And who knows? Next year we might get two. And certainly, I can say that the legend is female."
A sale for the first of the event's roughly 135,000 tickets was supposed to begin on Thursday but was pushed back "out of fairness" due to some confusion over the registration process.
"Unfortunately, it has come to light that some individuals hoping to buy tickets for 2024 have discovered after Monday's registration deadline that they are no longer registered, despite believing they were," the organisers said.
"Out of fairness to those individuals, we will be re-opening the window for registration at 12 noon on Monday 6 November. It will remain open until 5pm on Monday 13 November."
Standard tickets for the festival cost £355 (plus a £5 booking fee) - £20 more than this year's event. An additional fee will be added for the coach transfer.
