About 700 mourners were expected at the Murray Brothers Funeral Home in southwest Atlanta on Wednesday.
Lamar Willis, Kelly's uncle, said he'll be missed.
"He was a beautiful person, he loved life. He was a good son, a good grandson, a good nephew. He just, he loved life. He loved the hip-hop world. He was excited about getting back on stage. He was getting ready to resume his career. I mean, everything just falls in place for him and then tragedy struck," Willis said.
The funeral will be held at 2 p.m. at Jackson Memorial Baptist Church.
