Levert was sent to jail last week for failing to pay child support and died late Sunday night at Lutheran Hospital in Cleveland, said coroner Frank Miller.
Miller said an autopsy will be conducted to determine the cause of death.
Gerald Levert was 40 when he died in 2006 of an accidental mix of prescription and over-the-counter drugs.
The Levert brothers and childhood friend Marc Gordon were part of the R&B trio LeVert. Their hits included "(Pop, Pop, Pop, Pop) Goes My Mind" and "Casanova."
