Michael Jackson arrived at the UCLA Medical Center in Los Angeles at 1:10pm this afternoon after reportedly suffering from cardiac arrest approximately two hours ago.

Captain Steve Ruda of the Los Angeles Fire Department told the LA Times that when paramedics arrived at Jackson's mansion, the king of pop was not breathing. Two SUVs followed Jackson's ambulance as he was rushed to the hospital and we're told by eyewitnesses that about ten people emerged from the two cars when they arrived.

An X17 photog on the scene tells us that when he attempted to snap shots at the hospital, he was immediately accosted by one of Michael's bodyguards who grabbed him by the throat and shoved him, yelling for him to "get away!"

Sources are now telling X17online that Michael Jackson may have in fact passed away!
