Michael Jackson reportedly died of cardiac arrest on Thursday. He was only 50.

Jackson was pronounced dead at 2:26 p.m. PDT (5:26 p.m. EDT) after arriving at a Los Angeles hospital in full cardiac arrest, said Fred Corral of the Los Angeles County Coroner’s office. The cause of death was not known and an autopsy would likely take place on Friday, he said.

This is a very sad day for his family and friends and all his fans. My heart goes out to his three kids. I hope that they will go to a loving family member and one who won’t be more interested with whatever MJ had left in his enormous estate.

Rest in peace, Michael Jackson.
