Chris Kelly of the '90s rap duo Kriss Kross has died of an apparent drug overdose on Wednesday.

The rapper was just 34-years-old when he died at this home in Atlanta, Ga.

"It appears it may have been a possible drug overdose," Cpl. Kay Lester, a spokesperson for the Fulton County police, told the Associated Press.

Authorities said that their conclusion was drawn from statements received from the scene as well as evidence at Kelly's home.

Lester said that police were called to Kelly's home Wednesday afternoon before he was transported to the Atlanta Medical Center, where he was pronounced dead.

No official cause of death has been released and the results of an autopsy are pending.

Meanwhile, Kelly was the second half of Kriss Kross, which also included Chris Smith. The duo was just 13 years old when rapper and producer Jermaine Dupri discovered them.

Kriss Kross went on to release the hit single "Jump" and even toured with Michael Jackson.

Furthermore, the group became well known for their signature style. Kriss Kross would give performances while wearing their clothes backwards, causing many fans to copy the trend.
