Forget about a fire starting in her heart, it's more like butterflies in her stomach when Adele steps on stage!
The singer was reported to be joining Beyonce on stage during her incredible set at Glastonbury, but had to pull out due to a throat infection.
Most performers would be devastated by the news, but Adele was releived as she struggles to perform in front of large crowds.
A close friend told Now Magazine how Adele's label are worried that this fear may prevent her from having the successful career she deserves.
"Adele's very emotional and that's why she's such an amazing artist, but her anxiety attacks are so bad in front of a huge crowd she can barely sing and she dislikes doing festivals for the same reason."
She is reported to have been relieved after her US tour was cancelled because of her illness.
