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.

Chris Kelly's public wake is under way at a funeral home in Atlanta, GA ... where mourners were greeted with an instrumental version of "Jump" ... TMZ has learned.
Friends and family members have been paying their respects to the Kris Kross rapper at the open-casket event all day long -- while final preparations are made for tomorrow's public funeral.
Although Chris kept faithful to his pants-backward style his entire adult life, his burial trousers were forward ... he was dressed in a black suit, white shirt and pink tie, sporting earrings and a goatee.
We're told Chris "Daddy Mac" Smith and Jermaine Dupri (who discovered Kris Kross) have not arrived to the wake ... yet. Sources tell us Smith is taking Kelly's death especially hard and is still trying to pull himself together.
Inside the casket, on a sign attached to the coffin lid, read the words: "Cause that's what I was born to do ..." lyrics from the Kris Kross hit "Warm It Up."
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.
A small group of family and close friends planned to gather later on at Chris's house.
We broke the story ... Kelly died on May 1 after a suspected cocaine and heroin overdose. He was 34.

One of Kelly's guests -- who also seems inebriated -- pulls out a camera and begins to record as a discombobulated Kelly struggles to rap along with music pumping through the speakers.
We're told the song is a track Kelly had been working on recently -- and includes the lyric, "We don’t stop, for nothing or nobody … look around you it's full of dead bodies."
Hours after the video was shot, someone in Kelly's home called 911 and told officials the Kris Kross rapper passed out and wouldn't wake up. He was pronounced dead around 5:00 PM.

Fueled Drug Spiral
5/3/2013 5:00 AM PDT BY TMZ STAFF
Kris Kross' recent comeback ... and the money that came with it ... put Mac Daddy on a drug-fueled road to self-destruction, sources close to the deceased rapper tell TMZ.
Sources tell us, Mac Daddy -- real name Chris Kelly -- has been on and off drugs (including cocaine and heroin) for the last ten years, but had recently cleaned up his act.
We're told that changed dramatically in recent weeks, following Kris Kross' big comeback concert in Atlanta back in February.
According to sources, Kelly's ego blew up ... along with his wallet ... and he started hanging out in clubs again, chumming up with big name Atlanta rappers. We're told the drugs came back in full force as a result.
As we reported, Kelly's mother told police the rapper had been taking speedballs (coke and heroin mixed together) Tuesday night ... the night before he died ... and cops believe drugs contributed to his death.

Cocaine & Heroin Suspected
5/2/2013 7:55 AM PDT BY TMZ STAFF
11:22 AM PT -- A rep for the Fulton County Medical Examiner tells TMZ, the autopsy has been completed and there were no signs of trauma or foul play. The cause of death will be determined by the complete toxicology report in 3-4 weeks.
"Kris Kross" rapper Chris Kelly had been using a combination of cocaine and heroin the night before his death, this according to the police report obtained by TMZ.
According to the report, paramedics initially responded to Kelly's Atlanta home around 3 PM EST -- after his mother called 911 asking for medical assistance.
When help arrived, paramedics found 34-year-old Kelly lying on the living room couch -- unresponsive and with "no life signs." The medics attempted to revive Kelly, to no avail.
Kelly was immediately transported to a nearby hospital, where he was pronounced dead a few hours later.
After the death, cops spoke with Donna Kelly Pratte -- Chris' mother -- who told police ... the night before Kelly's medical emergency, he had taken a mixture of heroin and cocaine -- commonly known as "speedballs."
Donna told police she had personally taken Kelly home to recover from the drug use ... just as she had done several times before. Donna told cops Kelly had felt nauseous all morning before passing out.
According to the report, Kelly's mother and Kelly's uncle both told investigators the rapper had an "extensive history of drug use."
Hours before Kelly passed out, he had a phone interview with The Streetz Morning Grind radio show in ATL ... and sounded like he was in bad shape.
In fact, Kelly made reference to his hard-partying ways, which seemed to upset the DJ, who was personal friends with the rapper.
