Bee Gees star Robin Gibb is in a coma and gravely ill after contracting pneumonia, reported his website RobinGibb.com.

"Sadly the reports are true that Robin has contracted pneumonia and is in a coma. We are all hoping and praying that he will pull through," said in statement on his website.

The 62-year-old disco singer had recently seemed to have made a recovery after being diagnosed with colon and liver cancer. A spokesperson for the star said, "On Sunday 25 March, Robin Gibb underwent further intestinal surgery.” However, it is reported that things have taken a turn.

Gibb's wife Dwina, brother Barry, 65, daughter Melissa, and sons Spencer and Robin-John are at his bedside in a private hospital in Chelsea, West London, reports the Associated Foreign Press.
