The Fulton County Police told the AJC that Kelly's death is being investigated as a possible drug overdose. An autopsy will be performed Thursday morning.

The duo was best known for their multi-million selling 1992 album "Totally Krossed Out" and the major hit "Jump," which spent eight weeks atop the Hot 100. Mac Daddy, as Kelly was known, and Chris "Daddy Mac" Smith famously wore their baggy clothes backwards. The duo performed at the 20th anniversary party for Jermaine Dupri’s So So Def label in Atlanta earlier this year. The group was producer Dupri's and the label's first big success.

The album topped the Billboard 200 and produced four singles including "Jump," "It's a Shame," "I Missed the Bus" and "Warm It Up," which reached No. 13 on the Hot 100.

They followed up with "Da Bomb" a year later, which failed to match the success of "Totally Krossed Out," but still sold over a million copies. Their third and final studio album, "Young, Rich & Dangerous," featured guest appearances by Da Brat, Aaliyah and Dupri.
