Heavy D died Tuesday after collapsing in his California home. He was 44.

The Westchester County-raised entertainer was taken by ambulance to Cedars Sinai Medical Center in Los Angeles about 11:25 a.m. and died 90 minutes later, cops told the Daily News.

Heavy D was conscious and talking when officers responded to a 911 call from his Beverly Hills condo, said Lt. Mark Rosen of the Beverly Hills Police Department.

Rosen said the portly rapper, whose real name was Dwight Arrington Myers, was having difficulty breathing as paramedics rushed him to the hospital.

The performer had just returned from Europe and was battling pneumonia, KTLA news in Los Angeles reported.

Rosen said Heavy D had come home from a shopping trip Tuesday and began laboring for breath as he walked into his condo building.

“He collapsed in an exterior hallway,” Rosen said. “There doesn’t appear to be any foul play. We believe it was medically related.”

The actual cause of death is pending an autopsy.

Born in Jamaica and raised in Mount Vernon, Heavy D rose to stardom in the 1990s as the frontman for Heavy D & the Boys.
