On Wednesday (20Feb13), Lil' Flip pleaded not guilty to three counts of possession of a firearm, narcotic possession, and speeding.

The hip-hop star previously vowed to fight the allegations, maintaining he has a licence for the gun and arguing the supposed marijuana cigarettes were actually Black & Mild tobacco cigars.
