Family Vigil For Bee Gees Star Robin Gibb
Doctors fear for legendary singer after he slips into a coma...
But the 62-year-old recently developed pneumonia and, according to The Sun, doctors now fear a second tumour may be present.
A family friend told The Sun: "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 thrhough such a dire situation, it would be Robin because he is a fighter. But this is a battle he will struggle to win."
Robin's wife Dwina, brother Barry, his daughter and two sons are said to be at his bedside at a private London hospital.
