The Bee Gees' Robin Gibb is in a coma, according to multiple British outlets.
Gibb, who has been widely reported to be battling cancer, developed pneumonia recently and has slipped into a coma, The Sun reports. His family and friends, including his wife Dwina, his brother Barry, 65, and his three children, kept vigil at his hospital bedside on Friday, according to the paper, which cites a family friend.
