Peter Andre has been rushed to a London hospital this week.
The 'Behind Closed Doors' singer awoke in the early hours of this morning (26.11.10) in agony and was taken to see medical staff.
He has had to cancel his scheduled concert at Plymouth Pavilions tonight and is currently being monitored.
A statement posted on his official website read: "Peter Andre was rushed to hospital in the early hours of this morning in excruciating pain. At present he is being monitored closely and being kept in for extensive tests and scans."
The pop star's manager Claire Powell also said: "We are very worried about Peter and at present we do not know what is causing him to be in so much pain. Peter is terribly disappointed that he is unable to perform at tonight's sold out opening night. At this time we have no more information though we are hoping Peter will be able to perform at Minehead tomorrow as planned. We will keep his fans informed via his website www.peterandre.com for further information on the situation."
One person who is concerned for Peter's wellbeing is his ex-wife Katie Price.
She revealed he had been hospitalised on her twitter page and sent her former spouse her best wishes.
Referring to Peter's management agency Can Associates - which is run by Claire - she wrote: "I'm told CAN are going to release a statement saying Pete been rushed to hospital with stomach pains! Why does press need to know! Hope Pete ok. (sic)"
In July, Peter collapsed while out jogging and earlier this month he revealed he was going for an MRI scan for a mystery illness.
The star - who has two children, Junior, five, and three-year-old Princess Tiaamii, with ex-wife Katie - said: "I'm sorry to say that I haven't been feeling too great these last couple of weeks. I don't know what's wrong with me but I've got some ongoing health problems, and I've been having lots of tests at the hospital. I also had an MRI scan last week, so hopefully the doctors will get to the bottom of it soon. I just don't feel right."
