Kriss Kross rapper Chris Kelly - who performed under the name 'Mac Daddy' has died aged 34.
Kelly died on Wednesday after being found unresponsive at his Atlanta home, the Atlanta Journal-Constitution reported.
Fulton County police corporal Kay Lester told the newspaper Kelly's death is being investigated as a drug overdose, though an autopsy is planned on Thursday to determine the official cause of death.
Investigator Betty Honey of the Fulton County Medical Examiner's office told the Associated Press Kelly was pronounced dead at around 5pm at the south campus of the Atlanta Medical Centre.
Kelly performed alongside Chris Smith, aka 'Daddy Mac' in the early 90s. The pair were best known for the song Jump from their 1992 debut album Totally Krossed Out.
The pair eventually went their separate ways after releasing two further albums, reuniting in February to perform at the 20th anniversary concert for the So So Def label.
Musicians including P Diddy and LL Cool J have been paying tribute to Kelly on Twitter.
