Legendary R&B singer Gerald Levert died today from a heart attack. He was 40-years-old.

With his smooth tenor and gimmick-free performances, Gerald Levert became one of the most renowned singers of his generation, with a strong cult-like following, especially amongst women. On July 13, 2000, a Birmingham Alabama woman named Telisha Johnson, founded the sorority G. Phi G.in honor of Gerald Levert. G. Phi G. now has chapters (or what they refer to as Lairs) in nine major cities.

As the son of O'Jay's member Eddie Levert, Gerald Levert came from a very musical family, which he put to use as a member of the trio LeVert, with his good friend Marc Gordon and brother Sean Levert. In 1991, after recording such hits as "Casanova" and "Pop Pop Pop Goes My Mind" with the group, Gerald broke out on his own, releasing his solo debut Private Line. He would also join and collaborate with other groups such as LSG, which featured fellow R&B stars Johnny Gil and Keith Sweat.
