Kris Kross Rapper Official Cause of Death Overdose

It's not surprising, but it's official ... Kris Kross rapper Chris Kelly died from a drug overdose.

An investigator from the Fulton County Medical Examiner's Office in Atlanta said a toxicology screening showed the 34-year-old died with a fatal mixture of drugs in his system.

The investigator didn't specify which drugs, but as we reported, Chris' mother told police the rapper had been doing cocaine and heroin the night before he died on May 1st.

The video TMZ posted -- showing a wasted Chris trying to rap just hours before his death -- appears to back up the Medical Examiner's findings.

In addition to the footage, Kelly also had a long history of drug abuse.

The casket was flanked by photos of Chris and Daddy Mac in their heyday.

No media were allowed inside, though the viewing was open to the public ... one vehicle rolled up with "Jump" blaring out the windows ... a few local news trucks were parked outside ... but otherwise it's been a quiet affair.
