Rumours are swirling at Worthy Farm as excitement builds for Elton John's set featuring four secret guests. The legendary musician has already confirmed that he won't be alone on the Pyramid Stage tonight (Sunday, June 25), and some fans now think they've spotted a trail of clues hiding in plain sight.
As Glastonbury Festival revellers wake up to the last day at Worthy Farm, the hot topic is who the surprise acts will be. Britney Spears and Dua Lipa are among the top predictions as they have worked on songs with Sir Elton, but there could be a pattern emerging that points to others too when he takes the 'legends' slot from 9pm.
It will be Sir Elton's first Glastonbury performance but could also be his last ever live performance in the UK, as his farewell tour draws to a close. Earlier this week, David Furnish said his husband would be joined by "four collaborators of his choosing" but that he was "sworn to secrecy" about their identities.

While it may be a coincidence, spectators who frequented the Pyramid yesterday picked up on several cover songs that other big acts performed, and think it could be a clue that the original artists will be joining Sir Elton. It began with Rick Astley, who delighted the crowd by playing a rendition of As it Was by Harry Styles.
Many had already predicted that Harry Styles might make an appearance this weekend - Sir Elton is a big fan of the former One Direction star and recently revealed he would "love" to work with him. Harry Styles is currently touring Europe, with no clash tonight.
He played in Belgium last night (Saturday) then his next show is not until Tuesday in Germany, potentially giving him time for a quick pitstop in Pilton in between. Later in the day, Lizzo wowed fans yesterday with a spectacular set largely led by upbeat dance numbers.
However, she slowed it down with a brief take on Coldplay's Yellow and later took up her flute to assist with a performance of her song Coldplay. She told crowds that the British group was “one of my favourite bands”. Some fans think that could be a clue that Chris Martin is one of tonight's special guests.
Headlining the Pyramid Stage last night was Guns 'n' Roses, and there was talk on social media that Sir Paul McCartney would join them on stage for Live and Let Die. The Beatles legend had already been glimpsed at The Pretenders' star-studded show earlier in the evening, waving from the Park Stage.
The duet never happened but Guns 'n' Roses did go ahead with the Live and Let Die cover, which again could be a clue of things to come. That leaves just one guest left, if fans' theory about the pattern is correct.
Two of the leading predictions are Dua Lipa and Britney Spears, who have both worked on songs with Sir Elton. Britney was reportedly seen at Bristol Airport this weekend and had already fuelled speculation with an Instagram post, captioned with three British flags.
