British singer Adele has said she is "devastated" after being forced to cancel the final two shows of her world tour after damaging her vocal cords.
The 29-year-old performer had been due to perform at Wembley tonight and tomorrow night, ending a four-date run at the venue.
She wrote a heartfelt apology to thousands of fans who will miss out on seeing the star perform her last concerts of the year.
Vocal strain
In a post shared on social media, she said: "To say I'm heartbroken would be an understatement.”
"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 on both nights. I had to push a lot harder than I normally do."

The Hello singer had previously hinted that this tour would be her last.
The 29 year old included a handwritten note in the program for her Wednesday night show, saying that she misses home too much.
Medical advice
In her post on Twitter overnight she went to see a throat doctor on Friday night, who advised her not to perform over the weekend.
She said: "I'm already maxed out on steroids and aids for my voice.
"I've considered doing Saturday night's show but it's highly unlikely I'd even make it though the set and I simply can't crumble in front of you all and walk out on you in that way."
The star said she did not take the decision lightly, adding: "To not complete this milestone in my career is something I'm struggling to get my head around and I wish that I wasn't having to write this.
"It's something I'm really struggling to come to terms with,” she wrote. “It's as if my whole career has been building up to these four shows."
Sold out
Adele had already performed two nights to crowds of around 98,000 fans on Wednesday and Thursday night and tickets for her Saturday and Sunday shows were also due to be before capacity crowds.
She said refunds would be available to fans if shows cannot be rescheduled, signing off with: "I'm sorry, I'm devastated.”
"I'm sorry. I love you. I'm so sorry. Please forgive me x," she wrote.
