She will be performing on the Sunday in the "legend" slot.
Following a break last year to allow the land to rest, masses of music fans will today swarm into Worthy Farm for five days of music and entertainment.
Glastonbury has grown to become the largest music and cultural festival in the world, from much humbler beginnings.
We take a look at the statistics behind the Eavis family's backyard festival at Worthy Farm in Glastonbury.
This is an amazing piece of head gear. Love it.
It's hard work getting to Somerset, then queuing, and dragging all your stuff around.
Not long, fella. Tent up, little snooze, go again.
This sleepy chap is sporting some quite amazing headwear too. We like.
We've weaved together a really cool timelapse from this morning how how the tents appeared.
It's from the BBC's Glastonbury webcam that looks over the Pyramid stage.
It's worth noting that there appears to be an accident on the A37 at Wraxall.
It's not causing many issues according to Google Maps, but one to be aware of if you're heading that way.
The A361 is certainly getting a bit busier but Travel Somerset say it's only taking around 30 minutes to get into the car parks.
It must be great walking into Worthy Farm when you bought your ticket last October.
The anticipation, the excitement ... it's all coming out in Glastonbury's biggest smile.
We give you the happiest people we've spotted so far.
Around 200,000 festival-goers will start to descend on Worthy Farm in Pilton, Somerset today for the world's largest music festival.
BBC Somerset reporter Andy Bennett has been on site since Monday watching the finishing touches being made to the spectacle.
As ever, issues like consumerism, wastefulness and the unfairness in society will be on the agenda.
The Unfairground is the site for music "warped fairground side shows and iconic sculptural madness".
It may appear like a mirage in the heat and leave festival-goers blinking in confusion, but this year's event will feature a Victorian seaside pier for the first time.
Glastonbury-by-Sea has been created by designer Joe Rush in homage to the quintessential British seaside holiday destination.
The 70m re-purposed steel pleasure pier features arcades, attractions and sideshows.
Good news if you are on your way to the Glastonbury Festival the queues are much reduced on previous years.
At the moment the longest queue is between Glastonbury and the Worthy Farm site.
Don't forget to follow the festival signs and not your sat nav as many roads have one-way restrictions or are closed.
It's not taken long but hundreds of tents have already popped up.
All those who queued overnight and early this morning have hopefully got the prime locations they were after.
We love this last photo that shows a huge swathe of canvas up. It looks amazing!
You can see there's a little stop/start traffic on the A361 into Pilton, and the A37 to Cannard's Grave, but that's about it at the moment.
If you're in the area and want more updates do remember to tune to BBC Somerset on 95.5 FM.
There's some serious organisation going on with some Glastonbury campers this year.
We're thinking some kind of award for the best set of wheels might work?
Here's some of the best. The first guy has really planned ahead of time. Top marks!
