Robin Gibb battling liver cancer

Bee Gees singer Robin Gibb is reportedly battling liver cancer.

According to the Sunday Mirror, the 61-year-old was diagnosed several months ago and has been forced to cancel a number of public appearances in recent months due to his ill health.

Reports suggest Gibb was rushed to hospital earlier this week after emergency services were called to his home.

Mother Barbara and brother Barry are believed to have flown back from the US to be with Robin, who spent five hours in hospital on Tuesday.

A friend of the healthy living singer said, "Robin is not good and there is a lot of concern for him.

"... But Robin is a strong character, he is a fighter and has been encouraged by all the online messages from his fans. Dwina [his wife] is doing everything possible and hasn't left his side."

The source added, "There will be difficult times ahead but Robin will never give up and his loving family will make sure he has everything he needs."
