Dolores O'Riordan, Lead Singer of the Cranberries, Dies at 46

Dolores O'Riordan's publicist confirmed today that the singer died suddenly in London at the age of 46. Her cause of death has yet to be revealed. The Cranberries were set to go on tour in Europe last year, but the shows were cut short because O'Riordan suffered from back problems. She also had been previously diagnosed with bi-polar disorder.
