Chris Kelly was using drugs leading up to his death, according to TMZ. New information surrounding the Kris Kross rapper's untimely passing reveals he was using a combination of cocaine and heroin known as "speedballs."

Kelly's mother, Donna Kelly Pratt, reportedly told police that her son had been high off the drug cocktail one night before he died. His mother and uncle went on to tell authorities of Kelly's "extensive history of drug use," according to a police report.

Paramedics were called to the 34-year-old's Atlanta home yesterday afternoon. They found Kelly unresponsive on the couch and unsuccessfully attempted to revive him. He was later transported to Atlanta Medical Center's south campus, where he was pronounced dead.

"The family is trying to get beyond what has happened and we've lost him," Kelly's ex-manager Mike Mauldin told Fox 5 News. "That's basically where we're at right now."

Medical examiners have yet to release an official cause of death, which may not be available for several weeks pending toxicology reports.

An autopsy was performed on Kelly's body this morning.
