Rapper Chris Kelly from the rap duo Kris Kross, died Wednesday. He was 34.

Kelly was found unresponsive at his residence in Atlanta and later pronounced dead at an Atlanta hospital, CNN and TMZ report.

He passed away at 5:30 p.m. EST at the Atlanta Medical Center, according to TMZ.

Kross was an American rap duo of the 1990s comprising Chris "Mac Daddy" Kelly and Chris "Daddy Mac" Smith. The duo was best known for their hit 1992 song "Jump" and the "Rugrats Rap" which they sang for Nickelodeon.

"Jump" was #1 on the Billboard Hot 100 for eight weeks and was certified double platinum as a single. Kris Kross was also noted for their fashion style, which consisted of wearing their clothing backwards.

Kelly and Smith were discovered by Jermaine Dupri when they were performing at an Atlanta shopping mall and signed them to Ruffhouse Records where they released their first album Totally Krossed Out, in 1992. At the time, the rappers were only 13 and 12 years old respectively, according to Rolling Stone magazine.

Kriss Kross separated in the 90s. Most recently, in February, they reunited to perform at the 20th anniversary concert for Dupri's So So Def label, according to Rolling Stone.
