Pink just issued a blistering "warning" as she announces to fans she'll resume performing.

After being hospitalised for two nights, Pink has confirmed she’s been discharged and will resume performances starting with her upcoming Saturday show.

The singer issued an apology to fans on her Instagram and thanked them for their patience and thoughtful wishes.

“I want to say thank you to all of the kind people out there for your well wishes for my speedy recovery,” she said.

“On Monday, we were absolutely planning on going ahead with the show, and about 20 minutes before I left for soundcheck, I was rushed to the hospital, in excruciating pain.

“That was the reason for the late cancellation. It was out of anyone’s control, and of course, wasn’t planned that way.”

Hi beautiful Sydney people. First, I want to say thank you to all of the kind people out there for your well wishes for my speedy recovery. On Monday, we were absolutely planning on going ahead with the show, and about 20 minutes before I left for soundcheck, I was rushed to the hospital, in excruciating pain. That was the reason for the late cancellation. It was out of anyone’s control, and of course, wasn’t planned that way. I was discharged from hospital last night, and am following doctors orders of liquids and rest. A lot of you know how physical my shows are, and that I don’t just stand in front a microphone and sing. I flip, dance, fly, harness, silk, and scream my way through a total shit show of awesomeness (no pun intended). Therefore, I need to be physically healthy and well in order to perform this show. I think all of you deserve the full show and me at my best. Our next show will be Saturday, and until then I will be drinking green tea, and spending time with my kids. That’s a warning to paparazzi, you might actually see me walking upright outside of my hotel room cage with two little children, and another warning: I might even smile. Not too much, though. I’ll try to control the smiling. My sincere apologies to any of the ticket holders that this has affected, the rescheduled dates will be announced today. Thank you for your patience, compassion, and support. I look forward to rocking out with all of you as we have done for many many years. All of my love. Pink I also want to thank the amazing doctors and nurses at St Vincent’s Hospital for taking such good care of me and getting me home to my kids.

However, the 38-year-old wasn’t so nice to paparazzi and issued them this stern word of warning:

“Our next show will be Saturday, and until then I will be drinking green tea, and spending time with my kids,” she said.

“That’s a warning to paparazzi, you might actually see me walking upright outside of my hotel room cage with two little children, and another warning: I might even smile.

“Not too much, though. I’ll try to control the smiling.”

Zing.

This attack comes after Pink was photographed in Byron Bay with her daughter after cancelling her August 3 show on doctor’s orders. This led some fans and media to speculate she did this to spend time with her family at the beach-side town – a claim she quickly refuted in a previous Instagram post.

“I don’t need to clear this up, but out of respect for my fans I will attempt it. I scheduled this tour meticulously, trying to do what was best for my children, while also putting on the best and most physically demanding and beautiful show of my life,” she wrote.

“This break in Byron has been scheduled since 2017, as a way to get outside the hotel and the winter and have some time with my children.

“I have never f**ked off while disrespecting hard working people who spend money to come see me play. I have never phoned in a single tour, I have an impeccable record for not cancelling.”

During her illness, fans were told Pink suffered from respiratory and gastric issues, but now Michael Coppel – her promoter from Live Nation in Australia – has shared the full extent of her health problems.

“She suffered very serious attacks. She couldn’t breathe and was doubled over in pain and had to be taken to hospital in an emergency ambulance,” he told the Herald Sun and said she’s “still quite weak” despite being discharged.

“By that time, doctors were able to diagnose her based on the results from tests they had done the night before.

“She wasn’t waiting to see if and when she would be able to perform when she was struck down with the virus. How a virus affects someone is not predictable at all.

“This is not a show you can do unless you are 99.9 per cent match ready and she’s not there yet so we will give her this week to recover.”

The rescheduled dates for the Sydney shows have now been announced and are as follows:

Friday August 3 ticket holders will be rescheduled to Friday August 24.

Monday August 6 ticket holders will be rescheduled to Monday September 17.

Tuesday August 7 ticket holders will be rescheduled to Tuesday September 18.

Thursday August 9 ticket holders will be rescheduled to Wednesday September 19.

These date changes will also affect Pink’s concert on Thursday August 23 at the Brisbane Entertainment Centre and the performance has been moved to Wednesday August 22.
