C-Murder, the rapper who is serving a life sentence for murder, has slammed his ex-girlfriend Monica for publicly bashing him after their breakup.

The former No Limit Records star, whose real name is Corey Miller, posted a lengthy message on Instagram on Monday (December 11), accusing the R&B singer of being insensitive and selfish.

He wrote: "I don't know why someone feels the need to publicly bash a person that's fighting for their life?? I am a black male fighting and hoping for freedom one day. Wanna speak on something?? Let's talk about freeing us Louisiana inmates still held illegally and unconstitutionally by a racist Jim Crow law through a non-retroactive 10/2 non unanimous jury. Facts."
