Pink has been hospitalised with stomach flu.
The 'So What' singer took herself to a medical centre after falling ill, and tweeted a picture of herself in bed, sipping a drink with an intravenous (IV) drip attached to her arm.
She wrote underneath: ''Maybe it's cause my mum was an Emergency Room nurse all my life - but throw me in a gown and a hook me up to an IV- and I'm a happy girl. Stomach flu sucks but morphine doesn't (sic).''
After hundreds of people rushed to wish her well, the singer - real name Alecia Moore - gave her thanks, and clarified her previous comment, saying she was joking about the morphine, a strong painkiller commonly used on patients suffering extreme discomfort.
She wrote: ''Thanks for all the get well wishes. And no-they don't give morphine for flu. I might have ulcers again. Because I care too much. It's a gift.''
Pink is not the only pop star to have tweeted from hospital recently, as 'In Da Club' rapper tweeted a picture of himself surrounded by cuddly toys - including a giraffe, and elephant and a lion - in a hospital bed, after he too was taken in for treatment for a stomach virus.
Alongside the picture, he tweeted: ''I don't want to go into surgery.''
Rihanna has also tweeted a picture of herself hooked up a drip, after she was admitted to a medical facility suffering from fatigue.
