Lil Wayne's Lawyers Suing Tha Carter IV Stiffing Us in Private Jet War

EXCLUSIVE

Lil Wayne's legal team just added insult to his $2 million injury ... they say he owes them $80k for a legal case he lost!

Wayne's attorneys at Garbett, Allen & Roza just hit him with a lawsuit for unpaid fees. According to the docs, Weezy hired the firm to help him fight Signature Jets, which had sued him for, guess what -- unpaid bills.

As we reported ... Wayne lost that case, and has to fork over $2 mil to Signature. Now his lawyers want compensation for their legal representation ... despite the loss.

Wayne's counselors say they've already applied the $12,000 retainer he paid when he hired them back in Aug 2014, but he still owes $80,682.45.
