Michael Jackson who had been scheduled next month to begin the first of 50 sold-out concerts at London's O2 Arena died on Thursday of heart attack. Reports said that Jackson was rushed to UCLA Medical Center by paramedics responding to a call from his home at about 12:30 p.m.

The singer passed away Thursday afternoon at UCLA Medical Center. “The Los Angeles Fire Department responded to a medical emergency at 12:21 PM to the 100 block of Carolwood Drive,” Capt. Steve Rudha told RadarOnline.com. “We dispatched two paramedics and four firefighters who responded to the scene and treated the patient to the best of our abilities and transported the patient to UCLA.”

It's a regret he would not be able to perform for his fans ever again.
