Bee Gees star Robin Gibb was hospitalized earlier this week after suffering a setback in his cancer battle.
The 62-year-old musician, who has been undergoing chemotherapy treatment for colon cancer, was admitted to the London Clinic on Wednesday and has spent three nights under the care of doctors.
A representative for Gibb has confirmed the star is back in hospital, but insists the stay is a routine part of his treatment.
The spokesperson tells Britain's The Sun newspaper, "Robin is at the London Clinic as part of his treatment and rehabilitation."
Gibb recently revealed his doctors have been pleased with his recovery as his cancer is now "almost gone".
