Michael suffered a cardiac arrest earlier this afternoon at his Holmby Hills home and paramedics were unable to revive him. We're told when paramedics arrived Jackson had no pulse and they never got a pulse back.
A source tells us Jackson was dead when paramedics arrived. A cardiologist at UCLA tells TMZ Jackson died of cardiac arrest.
Once at the hospital, the staff tried to resuscitate him but he was completely unresponsive.
A source inside the hospital told us there was "absolute chaos" after Jackson arrived. One person who was there said "The staff responded in a way that looked straight out of 'Grey's Anatomy." People who were with the singer were screaming, "You've got to save him! You've got to save him!"
We're told one of the staff members at Jackson's home called 911.
La Toya ran in the hospital sobbing after Jackson was pronounced dead.
Michael is survived by three children: Michael Joseph Jackson, Jr., Paris Michael Katherine Jackson and Prince "Blanket" Michael Jackson II.
