Sad to hear the loss of my lil homie, Chris “Mac Daddy” Kelly. I met him and Chris “Daddy Mac” Smith in ’93. Their song “Jump” had been #1 on the billboard charts for eight weeks. Everyone knows Kriss Kross for their music and the crazy way they used to dress, but once they started working with So So Def, they became family.

Around 7:45 I received a phone call from his cousin saying they had found Kelly at the house just 20 minutes earlier and he was unresponsive.
