Robin Gibb Has Pneumonia, Is in a Coma
"Sadly the reports are true that Robin has contracted pneumonia and is in a coma," reads a statement on his website.
"We are all hoping and praying that he will pull through."
The singer's son Robin-John, told the Daily Mail, "My dad has had a hard recovery from cancer. When you get rid of the cancer a lot of periphery problems can occur. This is so sad."
In October 2011, the singer, who is 62, fell ill with intestinal problems. He was later diagnosed with liver and colon cancer, but had made a recovery. On Friday, however, it was reported that he'd been hospitalized again.
Robin's twin Maurice, who was also a founding member of the hit group, died of intestinal complications in 2003.
