Chris Kelly, Half of ’90s Duo Kris Kross, Dead at 34

Chris Kelly -- half of the kid duo Kris Kross, known for the 1992 hit song 'Jump' -- died in Atlanta, Ga on May 1. He was just 34 years old.

According to USA Today, the Fulton County Medical Examiner has yet to determine a cause of death.

Chris "Mac Daddy" Kelly (pictured left, above) and his partner Chris "Daddy Mac" Smith were originally discovered in 1990 at an Atlanta mall by legendary producer Jermaine Dupri, and the pair later became known for their trademark habit of wearing clothes backwards.

Their debut album 'Totally Krossed Out' featured the infectious single 'Jump,' which stayed on the top of the Billboard charts for eight weeks. That success sprung them into international fame, touring with Michael Jackson during the Dangerous World Tour and even getting their own video game for the Sega CD.

Although they never regained the heights of that first album, they released two more before breaking up and reunited briefly earlier this year to celebrate the 20th anniversary of Dupri's So So Def record label.
