Kodak Black Apologizes to PnB Rock's Girlfriend After False Blame

Kodak Black is attempting to right at least one wrong ... blaming PnB Rock's girlfriend, and her Instagram post, for his murder -- something he now regrets doing.

A clearheaded Kodak hopped on IG Live over the weekend to apologize to Stephanie Sibounheuang, the mother of PnB's children, after learning her post was not responsible for spurring the fatal armed robbery.

Kodak explained he had woken up with a migraine headache when he learned the PnB news on September 12, and says he made the immediate mistake of following the social media groupthink.

Kodak even went as low as to tell Stephanie to "kill herself" at the time, but he's now directly apologizing and wishing her peace going forward.

TMZ broke the story ... LAPD arrested a man named Freddie Lee Trone, his 17-year-old son and his wife -- and slapped them all with murder-related charges ... with the teen being named as the shooter.

The Florida rapper wasn't the only artist who jumped out the gate targeting Stephanie. Following the shooting, Nicki Minaj went on the attack -- but Cardi B screamed the complete opposite, and she's still calling for all offenders to apologize!!!
