Ailing Bee Gees star Robin Gibb has fallen into a coma and is fighting for his life in hospital, according to a U.K. report.

The 62-year-old singer is believed to have been diagnosed with a secondary tumor, just weeks after he confirmed his colon and liver cancer had gone into remission.

He has also developed pneumonia, according to Britain's The Sun.

A source tells the publication, "Our prayers are with Robin. He has kept so positive and always believed he could beat this. Sadly, it looks like he has developed pneumonia, which is very bad in his situation.

"If there is anyone you would put money on pulling through such a dire situation, it would be Robin because he is a fighter. But this is a battle he will struggle to win."

Gibb's wife Dwina, brother Barry, daughter Melissa, and sons Spencer and Robin-John are keeping a vigil at his bedside in a private hospital in London.

The singer is "gravely ill" according to a report in newspaper USA Today.
