Bee Gees star Maurice Gibb is seriously ill in a Miami hospital after suffering a heart attack. Doctors operated on the 53-year-old singer and bassist to remove an intestinal blockage after he collapsed at home, but he suffered a heart attack during surgery. Gibb, together with twin brother Robin and older brother Barry, was one of the biggest pop stars of the 1970s as part of the Bee Gees. He is understood to have started complaining of stomach pains on Thursday morning. His wife, Yvonne, and his two children are thought to be at his side as he recovers from the operation.
