Jessie J cancels Alnwick Castle concert
Pop star Jessie J has pulled out of a concert at Northumberland's Alnwick Castle after being hit by a virus.
She was due to perform on Saturday in front of an estimated crowd of 12,000.
Organisers KAL Music Limited said she was suffering from a viral infection, which doctors said was causing her "considerable fatigue".
A spokesman said the event had been rescheduled for 25 August, with all existing tickets valid. Refunds need to be arranged through ticket providers.
The spokesman added: "We would like to extend an apology to all concert ticket holders for any inconvenience caused.
"We are hugely disappointed to have to cancel Saturday's performance, but are pleased to have already confirmed an alternative date for the concert to go ahead.
"We hope that all ticket holders will be able to attend what is sure to be an incredible event. We wish Jessie J a speedy recovery."
A spokesman for the singer said: "Jessie is extremely upset to be disappointing her fans at such short notice, but looks forward to seeing everyone on the 25th August."
The singer was also forced to pull out of a performance on Friday evening at the Ponty's Big Weekend music event in Pontypridd, south Wales.
