Bee Gees singer Robin Gibb has undergone surgery, just weeks after declaring he was in remission from liver cancer.
The singer is now in hospital recovering after his operation on Sunday.
It is thought the singer is suffering from an intestinal condition, but reports about the cause of his hospital spell remain unconfirmed.

He was due to sing at the Royal Philharmonic's premiere performance of The Titanic Requiem in London on April 10, but has been forced to pull out all public appearances.
An spokesperson for the star has said: "On Sunday 25 March, Robin Gibb underwent further intestinal surgery.
"He is currently recovering in hospital and therefore, for the time being, all existing commitments prior to the Titanic Requiem concert, have had to be cancelled."
Last month the star told The Mirror he felt "fantastic" after his recovery.
"'I am beating cancer and can't wait to carry on with my work," he said.
