LOS ANGELES - Pop superstar Michael Jackson died Thursday after suffering a cardiac arrest.
The popular celebrity website TMZ said when paramedics arrived, the 50-year-old King of Pop had no vital signs. Emergency workers were unable to revive the singer, they reported.
Meanwhile, the LA Times has also reported Jackson "was pronounced dead by doctors this afternoon after arriving at a hospital in a deep coma."
Jackson was taken to hospital Thursday afternoon and TMZ reported that Jackson's father, Joe Jackson, said the King of Pop was "not doing well," shortly after he was brought to UCLA Medical Center.
Los Angeles Fire Department spokesman Capt. Steve Ruda told the L.A. Times that Jackson was not breathing when they arrived at his home.
Paramedics were called to a massive home on off Sunset Boulevard at about 12:20 p.m. According to the L.A. Times, Jackson rented the seven-bedroom, 13-bathroom mansion for $100,000 month.
Jackson was planning a comeback tour with a series of 50 sold-out shows at London's O2 Arena, with the first show scheduled to take place on July 13.
The first show was originally scheduled for July 8, but was postponed for five nights. Three other shows that were set for July were reportedly delayed until March 2010.
