Adele has been forced to cancel her final two concerts at Wembley Stadium in England after damaging her vocal cords.
The singer had already performed two homecoming shows at the London venue and was set to complete the four night run over the weekend.
In a heartfelt apology to fans, Adele made it clear that she didn't want to cancel the final two shows, but was advised to by her doctor.
In a letter she posted on Twitter she said, "I don't even know how to start this...the last two nights at Wembley have been the biggest and best shows of my life."
She went on to admit that she "struggled vocally both nights" and "had to push a lot harder" than normal.
Adele explained, "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 am simply unable to perform over the weekend. To say I'm heartbroken is an understatement."
Even though she considered performing the last two dates, she doesn't feel as though she could make it through either set.
Adele added that refunds will be available if the shows can't be rescheduled and said, "There will be more information over the next few days. I'm sorry. I'm devastated. I'm sorry. I love you I'm so sorry, please forgive me x."
If the shows can't be rescheduled, Adele may have already performed her last ever concerts.
Adele shared a letter to her fans deep within the official Wembley program, where she wrote, "I wanted my final shows to be in London because I don't know if I'll ever tour again and so I want my last time to be at home."
Regardless, Adele wrote in the letter that she "will always write music and will always put it out," so this is definitely not the end for the singer.
