The singer announced on Saturday that she would be postponing her Sunday night concert in Detroit, Michigan, due to illness, shortly after postponing another appearance on her Beautiful Trauma tour in Canada just days before.
"I've just seen the doctor here again in Montreal," she wrote in a note posted on Twitter. "I’m not going to be well enough to do the show tomorrow night in Detroit. I want to give you all the full show and not be hacking all the way through it and have to cut songs because of my voice."
"I am absolutely GUTTED to announce that tomorrow's show, March 23rd (Friday) will be postponed," Pink wrote in a statement. "I will absolutely be back to perform for you all and I'm grateful for you wanting to come and be with us at all."
Pink explained that her "entire family have been battling this awful virus/flu for two weeks now, and I have battled my way through these shows because postponing sucks."
"I'm really sorry and know that I have done everything I could to avoid this," Pink wrote, adding that her husband, Carey Hart, has been "sent home with the flu" as she and their two children -- 6-year-old daughter Willow and 1-year-old son Jameson -- are also battling illnesses.
"I wish anyone out there going through this healing vibes and big hugs," she concluded. The next planned stop on the tour is at the KFC Yum! Center in Louisville, Kentucky, on March 27.
While ill, Pink did take some time on her social media to support those participating in the March For Our Lives over the weekend. The singer shared an image on Instagram of a protest sign, with the caption, "A change gon’ come."
