Adele was due to appear alongside Beyonce during her headline appearance at the Glastonbury Festival – but was ordered to pull out by doctors, it's been reported.
The singer, who has been battling voice problems, was apparently invited to join Beyonce on the Pyramid Stage.
But doctors warned her that she needed to protect her throat to prevent any long-term damage.
A source told The Sun: “Adele was absolutely gutted, Beyoncé is one of her big heroes. It would have been the stuff of dreams to perform with her - the gig of her life.
“But docs have told her she's got to rest her voice or risk damaging her prized asset. She hopes one day they can do something together.”
