C-Murder is serving a life sentence for the assault and murder of 16-year-old Steve Thomas in 2002.
But he can still keep in touch with the rap game from his prison cell.
According to Master P's bro, NBA YoungBoy is now the realest in the game.
"I want to ask the older cats to stop hating on our new generation that rap. These dudes really eating and it's all legal," he typed. "NBA Youngboy keeping it realer with me than any n*gga I know. However it go, I'm rolling with him in war or peace. He's my Soulja Slim of the new generation."
Last year, NBA YoungBoy paid tribute to C-Murder by remixing his 1999 track "Like A Jungle."
C-Murder gushed about YB after he heard it.
"I never felt this way about a song. U literally made my heart stop. u did like a jungle real justice. It made me feel so good to know I am not forgotten and recognize by someone so real. I salute u until I am in the casket and after. Forever tru," he said at the time.
