TMZ reports that Michael Jackson has died in UCLA Medical Center:
We've just learned Michael Jackson has died. He was 50.
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.
Once at the hospital, the staff tried to resuscitate him but he was completely unresponsive.
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.
At this point the only other news source that is reporting this is BNO News, which reports that OK! magazine is also reporting Jackson's death:
Michael Jackson, often referred to as "The King of Pop", died at the age of 50 on Thursday afternoon after suffering a cardiac arrest, news reports say.

The cause of death was not immediately known. Both OK! Magazine and TMZ.com confirmed his death.
At this point Fox News is holding off reporting anything further until they confirm it with authorities.

Update II: The LA Times is now reporting Jackson is dead. He was pronounced dead at 3:15pm PDT, 6:15pm EDT.
