Adele has shared a big announcement about the rest of her 2017 UK tour on social media. In an emotional message posted on Instagram on Friday, the Hello singer revealed that she had to cancel her remaining tour dates, set for July 1 and 2 at London's Wembley Stadium.

The Hello singer has temporarily damaged her vocal cords, which forced her to cancel the last two nights of her tour. She wrote on Instagram, "The last two nights at Wembley have been the biggest and best shows of my life. To come home to such a response after so long away doing something I never thought I could pull off but did has blown me away. However, I've struggled vocally both nights."

Hello songstress, who performed to around 90,000 fans at the London venue on 28 June, continued, "I went to see my throat doctor this evening because my voice didn't open up at all today and it turns out I have damaged my vocal cords. And on medical advice I simply am unable to perform over the weekend," Skyfall singer penned in an emotional post.

The singer goes on to add that she is "heartbroken" and has apologised for disappointing fans. "To say I'm heartbroken would be a complete understatement. I'm sorry for your disappointment. I'm sorry for the nights you would have had with your loved ones and the memories you would have made together. I'm sorry for the time and money you've spent organizing your trips," she said.

The 29-year-old added that refunds will be available if the shows can't be rescheduled and promised that there will be more information over the next few days. She concluded the lengthy Instagram post by saying, "I am sorry. I am devastated."

Adele has been open about her struggle with touring in the past, admitting that she suffers from stage fright. The Someone Like You singer was forced to cancel her world tour in 2012 to undergo surgery on her vocal chords and later made a comeback in 2015 with a new album, 25.
