Lil Wayne is enjoying his freedom before he starts a jail term for possessing an illegal gun. The rap superstar — who pleaded guilty last week to possessing a .40-caliber semi-automatic cops found in a Louis Vuitton bag on his tour bus outside the Beacon Theatre — was spotted at Miami hot spot Liv on Sunday night. A spy said Wayne was living it up alongside rapper Nelly and added, “They were with a big group of women and stayed until 4 a.m.” Wayne needs to get all his partying done before February’s sentencing, when he’s expected to be handed a year in jail.
