Emily Eavis has teased there will be several "secret sets" at Glastonbury this year.
The Somerset festival's organiser says there are plans to celebrate 10 years of the famous The Park stage, which has seen the likes of Guy Garvey, Ryan Adams and Rag 'n' Bone Man grace in the past, with special and extremely confidential performances planned.
Speaking to NME magazine, Emily - who manages the acts playing with her father Michael Eavis - spilled: "It's 10 years of The Park, so there's gonna be some stuff out there. I guess there's a few artists who come and get a feel for it, who are going to try and doing something a bit off the beaten track. There will be a couple of those appearances, but I can't give too much away on that side."
With rumours still swirling about who could be set to perform this year, Emily insisted that many of them are "ludicrous" and suggested they still haven't decided on who could bet set to storm the stage.
Pressed for who could be set to surprise festival-goers, she said: "Well, it could be anyone, couldn't it? The rumours are ridiculous here. I think it's something to do with all being fenced in and away, away from the outside world for five days. So anything's possible.
"Any ideas about what's happening in the outside world are so ludicrous and so all these rumours circulate. I don't know what they could be this year, who knows?"
The blonde beauty recently confirmed that Blossoms are confirmed to perform on the Pyramid Stage.
She said: "We just confirmed Blossoms for the Pyramid Stage as well, which is great. They are one of our favourite new bands from 2016. They played at Pilton Party last summer, which is our special event to say thank you to the locals."
They join headliners Ed Sheeran, Foo Fighters and Radiohead.
Katy Perry, Stormzy, Bee Gees legend Barry Gibb, The xx, Royal Blood, Biffy Clyro, The National, Chic, Major Lazer, Lorde, The Jacksons, The Flaming Lips, Emeli Sande, Halsey, George Ezra and Kaiser Chiefs are also on the bill.
