According to police investigators, 34-year-old Kelly was pronounced dead around 5 p.m Wednesday at the south campus of the Atlanta Medical Center.

At this time, the cause of death has not been determined. Chris 'Mac Daddy' Kelly, was one-half of the 90s duo Kriss Kross with Chris 'Daddy Mac' Smith. The two were 13 years old when discovered by So So Def head honcho Jermaine Dupri at an Atlanta mall in 1991.

The pair, recently reunited at a So So Def 20th anniversary party, were best known for their backwards clothing style and the hit song "Jump" from their 1992 debut album, "Totally Krossed Out."
