Before TMZ reported Jackson's heart attack, the site said it had been told by friends that Jackson, who turns 51 in August, was in "really bad shape".
The site said his father, Joe Jackson, had also confirmed to TMZ that his son was "not doing well".
The Los Angeles Times reported Jackson's condition was grim.
"Captain Steve Ruda said paramedics responded to a call at Jackson's home around 12:26 pm," the Los Angeles Times said.
"He was not breathing when they arrived. The parademics performed CPR and took him to UCLA Medical Center.
"Paramedics were called to a home on the 100 block of Carolwood Drive off Sunset Boulevard. Jackson 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."
