The wife of Bee Gees star Robin Gibb has dismissed rumors he's fighting for his life as he battles cancer, insisting he's "doing brilliantly" and "feels good" following chemotherapy treatment.

The singer was hospitalized in November, just weeks after he was treated for abdominal pains and inflammation of the colon, and subsequent reports suggested he had been diagnosed with liver cancer.

Gibb originally refused to shed light on his condition, but his spokesperson revealed earlier this week that he is in fact undergoing chemotherapy sessions, used to destroy cancer cells.

His representative, Mick Garbutt, said, "It is true to say he is very unwell, but he's an incredible man and enjoys lots of support from his close circle of friends and family, and particularly from his wife Dwina. He is receiving regular chemotherapy and fighting hard."

The reports caused fans to become concerned about the state of his health, but his wife Dwina has reassured them the "Stayin' Alive" hitmaker isn't suffering and plans to continue working.
