(CNN) Pink was not ready to get the party started in Australia over the weekend, after a virus landed the singer in a hospital. 
 
 Pink has been admitted to a hospital in Sydney twice since Sunday, suffering from dehydration and a gastric virus, according to Live Nation, her concert tour promoter. 
 
 After initially checking in Sunday evening and being discharged, she was readmitted Monday and canceled Monday night's performance, Live Nation said in a statement released hours before she was set to take the stage.

 SYDNEY (AP) — Pop superstar Pink was admitted to a Sydney hospital on Monday with a virus, forcing her to postpone a second show, her promoter said. 
 
 The singer's "Beautiful Trauma" world tour's first concert in Sydney was scheduled for last Friday, but she canceled that show on doctor's orders. 
 
 She battled through a Saturday night show. 
 
 Promoter Live Nation tweeted that Pink was admitted to a hospital on Sunday suffering from dehydration and was discharged. But she was readmitted and diagnosed with a gastric virus hours before her Monday concert. 
 
 "Pink will remain in hospital overnight, continuing her treatment and recovery," the tweet said. 
 
 Both the Friday and Monday night shows are expected to be rescheduled. 
 
 Pink's Australian tour is scheduled from July 4 to Aug. 26. 
 
 Pink last toured Australia in 2013 when she performed 46 shows as part of her "Truth About Love" world tour.
– Pink was admitted to a hospital in Australia on Monday with a virus, forcing her to cancel a second show, per the AP. The pop star is in the country as part of her world tour for the album "Beautiful Trauma," but a Sydney stop was canceled Friday. Live Nation tweeted that Pink was admitted to a hospital on Sunday suffering from dehydration and was discharged before being readmitted. On the second go-round, Pink was diagnosed with a gastric virus and hours before a Monday concert that show was canceled, too. "Pink will remain in hospital overnight, continuing her treatment and recovery," the promoters tweeted. Both shows are expected to be rescheduled. Meanwhile, a paparazzi photo taken in the days between the canceled shows forced the singer to issue a public statement defending herself. In one shot, Pink is seen on one of Australia's famous beaches along with her daughter. The country's Daily Telegraph ran the photo with the headline "Pink's Sydney Concert Cancelled as She Chills in Byron Bay." While sharing the headline and photo on her own Instagram, Pink responded by offering a heartfelt statement about parenting while sick with sick kids. "I’ve already been sick twice (kids as well) on this Australian tour, but the first time we got sick, I was able to push through," she wrote, per CNN. "What these parasite paparazzi don’t show you, is two doctor visits in Byron on two consecutive days."
