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...

Fans and paparazzi converged on Michael Jackson's family homes and UCLA Medical Center on Thursday, blocking streets and blasting the singer's music as they waited for news or a glimpse of the superstar's famous family.

In Hollywood, about 75 fans gathered at what they believed was Jackson's star on the Walk of Fame, only to discover it belonged to the Los Angeles radio personality of the same name. The singer's star was covered by scaffolding for the premiere of "Bruno." So his fans stayed put, covering the surrogate star with flowers and candles and singing the hit by Jackson and Lionel Richie, "We Are the World."
