Original story: Very sad news as Chris Kelly of rap duo Kris Kross is dead at 34.
Chris was found unresponsive in his home in Atlanta on May 1, according to CNN.
He was rushed to an Atlanta hospital and pronounced dead.
The cause of death is currently unknown, but more details will likely surface after the planned autopsy on Thursday.
Chris — also known as "Mac Daddy" — and Chris Smith were the two members of the child rap duo who had huge success in the early '90s with their songs "Jump" and "Warm It Up."
The group's debut album, Totally Krossed Out, was released in 1992 when Chris Kelly was 13. The album went four-times platinum in the U.S.
Part of their success was linked to the fact that they would wear their clothes backwards for some reason.
But the group never saw much commercial success after that. Their second album, Da Bomb, went platinum a year later but failed to register any big hits.
They released one last album as a duo in 1996 before going their separate ways to pursue solo careers.
Kris Kross reunited for a one-night-only performance in Atlanta in February 2013 to celebrate the 20th anniversary of their label.
Our thoughts are with his family and loved ones during this difficult time.
