Adele reportedly was supposed to share stage with Beyonce Knowles at the Pyramid Stage of Glastonbury Festival over the weekend. She, however, was forced to back out of the gig because she was advised by doctor not to sing in order to avoid long-term voice damage.
"Adele was absolutely gutted, Beyonce is one of her big heroes," a source told The Sun. "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."
Earlier this month, Adele scrapped remaining dates of her North American tour "under doctor's orders" after she was diagnosed with laryngitis. "I'm really frustrated. I'm so sorry," she stated back then. "I was hoping with a weeks rest I'd be better to sing again straight away." Three weeks later, she announced make-up dates for the canceled concerts, rescheduling them for August and October shows.
Still, she hadn't recovered well enough to return to the stage this month for the U.K. music festival. Instead of seeing her in Somerset, concertgoers were treated with surprise appearance by Beyonce's close pal Gwyneth Paltrow who has delved deeper into music by starring in musical series "Glee" and doing collaborations with some artists like Cee-Lo Green and Matthew Morrison.
