Australian singer Peter Andre was admitted to hospital in the early hours of Friday morning (26Nov10) after suffering "excruciating" stomach pains.
The Mysterious Girl singer was taken ill overnight and is being "monitored closely" by doctors at an undisclosed medical facility.
The star has also cancelled the opening date of his U.K. tour on Friday night in Plymouth, south-west England.
A statement from his management team, CAN Associates, reads, "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.
"Peter was due to play at Plymouth Pavilions tonight for the first night of his Arena Tour, however this has had to be postponed due to his current condition and will be re-scheduled for Tuesday 21st December 2010. We are hoping Peter will be able to perform at Minehead tomorrow (Saturday) as planned."
His manager Claire Powell adds, "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."
Andre's ex-wife Katie Price broke the news of the star's hospitalisation on her page, writing, "I'm told CAN are going to release a statement saying Pete (has) been rushed to hospital with stomach pains! Hope Pete (is) ok."
Earlier this month (Nov10), Andre sparked fears for his health by revealing he was battling a mystery illness and had been undergoing tests.
He said, "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."
