LONDON (AP) -- British media reports say former Bee Gee Robin Gibb is gravely ill with pneumonia in a London hospital.
The Sun newspaper reported Saturday that 62-year-old Gibb is in a coma, citing a family friend.
Gibb's publicist, Doug Wright, declined to comment, but Gibb's son has acknowledged that the 62-year-old musician is seriously ill.
Gibb was hospitalized last year for stomach and colon problems and had intestinal surgery last month.
He was forced to miss the London premiere of his classical "Titanic Requiem" this week because of illness. His son Robin-John Gibb said the family was "praying for him and hoping he has a speedy recovery."
The Bee Gees -- brothers Robin, Barry and Maurice Gibb -- had a string of disco-era hits including "How Deep is Your Love" and "Stayin' Alive."
