Music icon Michael Jackson, whose fame spanned from his childhood with the legendary Jackson 5 to a superstar solo career that earned him the nickname ‘King of Pop,’ died Thursday afternoon at a Los Angeles hospital, a source close to the family told FOX News. He was 50.

Debra Opri, a former Jackson family attorney, confirmed the singers death after other media reported that he had fallen into a coma. He reportedly was taken by ambulance at 12:30 p.m. local time to UCLA Medical Center, where he died at 3:15 p.m.

Multiple reports said he had gone into cardiac arrest, though the official cause of death wasn’t immediately known. A news conference is expected later Thursday at the hospital, where fans have gathered to pay tribute to the singer.
