Chris “Mac Daddy” Kelly, one half of the 90’s rap duo Kriss Kross, has died in Atlanta. Authorities in Georgia confirmed the sad news to both The Associated Press and The Huffington Post just moments ago. He was 34 years old.

According to AP, Kelly was pronounced dead at around 5 p.m. Wednesday evening at the south campus of the Atlanta Medical Center. Investigator Betty Honey of the Fulton County Medical Examiner’s office said authorities weren’t sure of Kelly’s cause of death, and that an autopsy has yet to be performed.

CBS Atlanta is reporting that Kelly, a longtime sufferer of leukemia, was found dead at his home in Atlanta.

Chris Kelly, who went by the rap name “Mac Daddy,” performed alongside his best friend Chris “Daddy Mac” Smith throughout the early and mid-90’s as the rap duo Kriss Kross. The pair might best be known for the hit song “Jump” from their 1992 debut album ‘Totally Krossed Out.’
