Tonight  (March 7) marks the premiere of Nelly’s Behind The Music episode on VH1.

The Emmy-nominated series will focus on the St. Louis native's decade long career that includes albums like Country Grammar and his latest, 5.0. The hour long show will find the 36-year-old rapper addressing his career, his relationship with singer Ashanti and the untimely death of his sister to Leukemia.

“Nobody around me was telling me the truth, that she was not going to make it,” Nelly says in the special. “The day that she died I talked to her about 20-25 minutes, she gets off the phone, lays down and then she was gone.”

Be sure to tune in to Nelly's Behind the Music tonight at 10 p.m. EST. Nicole LoPresti
