Pop superstar Pink has been forced to postpone another Sydney show as she recovers from a gastric virus in hospital.

Promoter Live Nation said Tuesday’s performance at Qudos Bank Arena won’t go ahead based on medical advice.

The American singer was admitted to St Vincent’s Hospital in Sydney on Sunday night with dehydration but later discharged.

The 38-year-old was readmitted on Monday and diagnosed with a gastric virus.

“Pink remained in hospital overnight, continuing her treatment and recovery. She will be reassessed by her doctors today,” Live Nation said in a statement on Tuesday.

Pink cancelled her first Sydney show on Friday night on doctor’s orders, but battled through a performance on Saturday night.

The American singer’s Beautiful Trauma world tour was due to hit Sydney on Friday but she cancelled that first show on doctor’s orders.

She went ahead with a Saturday night show, but on medical advice postponed Monday night’s concert just hours before it was due to start at Qudos Bank Arena.

All other performances on the Australian leg of Pink’s Beautiful Trauma tour will go ahead as scheduled, Ticketek said in a tweet on Monday.

Pink kicked off her latest Australian tour in Perth from July 4. She then played in Adelaide and Melbourne before Sydney, where further shows are scheduled on August 9, 11, 12, 25 and 26.

She’s also due to perform seven shows in Brisbane between August 14 and 23, followed by Melbourne again on August 28 and 29.

Pink last toured Australia in 2013 when she performed 46 shows as part of her Truth About Love world tour.
