Tickets to Glastonbury Festival have already sold out - but so far just one act has been confirmed for its line-up.
The festival will return to Somerset from June 21 to 25 next year.
Elton John has been announced as the first headliner for Glastonbury Festival 2023.
He will appear on the Pyramid Stage on Sunday - with the show set to be his last-ever UK date following his Farewell tour.
Who is rumoured to headline and perform at Glastonbury Festival this year?
Elton John is the only confirmed act for Glastonbury Festival but Arctic Monkeys, Harry Styles and the Spice Girls are among other the heavily rumoured acts. Other names such as Taylor Swift and Eminem have also been mentioned - here's the latest list...
The Arctic Monkeys are no stranger to the Pyramid Stage, having headlined the festival in 2007 and again in 2013.
They are among the bookies' favourite to headline, having just announced a tour of the UK and Ireland in 2023 ahead of the release of their new album The Car.
But it's the dates of their tour which have got people talking - there is a gap during Glastonbury Festival.
The band will play a gig in Marlay Park in Dublin the day before the festival starts, on Tuesday 20 June, with their next gig in Glasgow not until the final day of the festival - on Sunday 25 June.
Harry Styles was a huge rumour for the 2022 festival, having performed in front of massive crowds on his world tour.
But the star failed to pop up on any of Glastonbury Festival's stages, meaning people are now convinced he was holding out for a 2023 headline slot.
Harry Styles' Love On Tour will continue into next year, with him returning to the UK for a series of gigs in June.
He is due to perform two gigs in Cardiff in the week of Glastonbury, with two nights off from the tour on Thursday 22 June and Friday 23 June.
It means fans are convinced he'll be the Friday night headliner, before jetting off to Belgium for his next tour date on Saturday 24 June.
Pop icon Taylor Swift was due to headline Glastonbury Festival in 2020 but the event got cancelled for two years running due to the pandemic.
While organiser Michael Eavis said he had secured many of the same acts for 2022 as were planned for 2020, Taylor Swift's name did not re-appear on the bill.
But the singer-songwriter is due to release a new album this year, sparking rumours of a tour and potential Glastonbury visit.
Glastonbury Festival 2022 was filled with nostalgic acts, with names such as TLC, the Sugababes and McFly drawing such big crowds they saw stages and fields closed off.
Mel C was one of those nostalgic names to attract a huge crowd when she performed a DJ set at William's Green. She then made another surprise appearance with Blossoms on the Other Stage.
She has since fuelled rumours that all of the Spice Girls could reunite for the legends slot at Glastonbury Festival 2023.
Speaking to BBC Breakfast, she said: “It’s the dream, the absolute dream, yeah, we would love to do it...
"You know what, the girls and I, we have chatted about it. You know, it’s the biggest stage in the world, we have the best festival in the world right here,” she added.
American rapper Eminem is said to be in "advanced talks" about headlining Glastonbury Festival 2023.
If proved to be true, it would be the first time the hip-hop artist has headlined the festival.
A source told The Sun newspaper: “Eminem is wanted for a huge slot at Glastonbury and has been in talks for yonks.
“His dates all line up and if they can get him on board, it will be the first time he has ever played at the festival."
