And some unlucky fans felt the wrath of Pink's temper when she addressed them in an open-letter blog this week after they lashed out at her for cancelling her Birmingham show.
She took to her official website on Saturday to explain the reasons behind the cancellation, comparing her less-than-polite fans to 'rabid dogs.'
'I am getting a lot of hate mail from some of you, not all. But to those of you that expect and feel entitled to perfection; Have a look at my track record,#' she wrote.
'I go on stage and pour my f***ing heart and body out on that stage. I ruin my body and my vocal chords, make myself sicker, come hell or high water.'
'I am a human being, therefore I am able to catch illness. It is beyond my control- and I can't apologize for that,' she added.
'And you know what I've been performing through the last week? ROTA virus. Look it up. I challenge any one of you to do what I do while sick with that. You couldn't do it," Pink explained.
Pink also pointed out that in the future, she'll wonder if her fans will turn on her again.
'The next time I schedule dates- ill have to say to myself- 'if, God forbid I have to cancel one show, those fans will turn on me like rabid dogs and question the moral fabric of my character.'
Concluding her letter, the star said: 'For the loyal and understanding fans, I am so so sorry if I've hurt you in any way.
