Sir Elton John excited fans when he announced special guests for his headline set at Glastonbury Festival on Sunday.
The 76-year-old Rocket Man singer will be headlining the yearly festival tonight and will be joined on stage by a few stars.
“I’ve got guests who I can’t tell you who they are,” he said.
“But it’s going to be wonderful – I’m really looking forward to it.”
After announcing the news, rumours have been swirling on the potential stars making a guest appearance on stage.
Some believe Britney Spears - who collaborated with him on Hold Me Closer last year - could be the surprise star.
Meanwhile, a music correspondent recently overheard Sir Elton's team doing their soundcheck and possibly figured out one of the guests.
Singer Rina Sawayama performed on the Woodsies stage on Saturday night but could be making a return on the main stage.
Hours before Sir Elton's set, music correspondent Mark Savage took to Twitter to announce: "Elton John's team just performed a soundcheck at Glastonbury.
"As one mic was being tested, a member of the crew said: "One, two, one two. Rina mic, one, two." So is that @rinasawayama confirmed for the Pyramid Stage tonight?"
In 2021, Rina and Sir Elton collaborated on an updated version of Rina's song, Chosen Family.
While performing her set on Saturday, Rina hit out at The 1975's frontman Matt Healy while introducing her song STFU!
"I wrote this next song because I was sick and tired of micro-aggressions. So, tonight, this song goes out to a white man who watches [pornography show] Ghetto Gaggers and mocks Asian people on a podcast," she said.
"He also owns my masters. I’ve had enough."
Matty was previously slammed for laughing at the racist comments made about Ice Spice in a February podcast with Adam Friedland and Nick Mullen.
Appearing on the show, Matt was taking part in a conversation that saw comments made about Ice Spice, which included remarks on her weight and ethnicity.
He was seen chuckling at comments, including comments calling her an "Inuit Spice Girl" and a "chubby Chinese lady".
Matty also discussed the time he masturbated to porn, called 'Ghetto Gaggers', of 'brutalised' Black women after a party.
He later addressed the comments to an audience in New Zealand, claiming he was “kind of a bit sorry.”
