Updated at 3:15 p.m.: Pop star Michael Jackson was pronounced dead by doctors this afternoon after arriving at a hospital in a deep coma, city and law enforcement sources told The Times.]

[Updated at 2:46 p.m.: Jackson is in a coma and his family is arriving at his bedside, a law enforcement source told The Times.

Jackson was rushed to Ronald Reagan UCLA Medical Center this afternoon by Los Angeles Fire Department paramedics.

Fire Capt. Steve Ruda said paramedics responded to a call at Jackson's home at 12:26 p.m. He was not breathing when they arrived. The paramedics performed cardiopulmonary resuscitation and took him to the hospital, Ruda told The Times.

[Updated at 2:12 p.m.: Paramedics were called to a home in the 100 block of Carolwood Drive off Sunset Boulevard. Jackson had rented the Bel-Air home for $100,000 a month. It was described as a French chateau estate built in 2002 with seven bedrooms, 13 bathrooms, 12 fireplaces and a theater.

The home is about 2 1/2 miles, about a six-minute drive, from UCLA Medical Center. An earlier version of this post incorrectly described the time to travel between the home and hospital as two minutes.]

The news comes as Jackson, 50, was attempting a comeback after years of tabloid headlines, most notably his trial and acquittal on child molestation charges.

In May, The Times reported that Jackson had rented the Bel-Air residence and was rehearsing for a series of 50 sold-out shows in London's O2 Arena. Jackson had won the backing of two billionaires to get the so-called "King of Pop" back on stage.

I don't think I've ever been hit this hard by a celebrity's death since Health Ledger. But Michael Jackson wasn't just a celebrity, he was a phenomenon! No matter what you think about his appearence, personal life or his public behavior, this man was one of the greatest entertainers of our time! The biggest selling album of all time, the best dancer of all time and a lifetime of countless achievements, it's an understatement to say he will be missed! The world of music literally won't be the same ever again!
