Lil Waynelost a lawsuit last month to a private jet company named Signature Group and forked over around $2 million in unpaid bills. But he's not done yet -- his lawyers from the case are now suing him for $80,000, claiming that Wayne never paid them their legal fees. 

According to documents obtained by TMZ, Wayne's legal team at Garbett, Allen & Roza have already applied the $12,000 retainer they received initially and are still owed $80,682.45.

Wayne has been receiving legal justice, he has also been dispensing it -- last week he sent cease and desist letters regarding a leaked sex tape, and that $51 million lawsuit against Birdman and Cash Money has yet to bet settled.
