The news of Kris Kross’ Chris Kelly’s death this week aged just 34 has taken an even sadder turn, after it was revealed that his mother, Donna Kelly Pratte and his uncle, Lamar Williams, had told police that they believed the rapper had taken cocaine and heroin on the night before he died, causing him to become sick.

As The Guardian reports, Kelly was found unresponsive on his living room couch at his Atlanta home they tried to resuscitate him. He was pronounced dead at a local hospital. Elsewhere, the man who presented Kelly and his Kris Kross partner Chris Smith to the world in 1992, Jermaine Dupri, paid his respects to the late artist. "To the world Chris was Mac Daddy but to me, he was a son I never had," Dupri said in a written statement. "When I think about it, I spent more time with Chris and Chris than damn near anybody in my whole life, so you can imagine how bad this hurts," Dupri added. "I will always love you Chris, and I will never let the world forget you, may God bless your soul."

Kris Kross achieved huge fame in 1992 when their single Jump went to the top of the US Billboard singles chart and stayed there for 8 weeks. Kelly was just 13 at the time and the pair were unable to keep up their success, before splitting in 1996 and going on to have unsuccessful solo careers.
