Lil Wayne - " No One's Taking My Crib and My Cars "

Lil Wayne is laughing at reports that he's about to lose his mansion and fancy cars to satisfy a $3.4 million judgment against him -- because he says that kind of jack is pocket change to him.

Wayne had sued Quincy Jones III over a documentary about the rapper's life. QJIII countersued ... claiming Wayne screwed him out of profits by acting so unreasonably.

The California jury saw it Quincy's way and slapped Wayne with the multi-million dollar judgment.

Now, Quincy's lawyer has moved the judgment to Florida ... where Wayne has lots of assets, including an $11 million mansion and a Bugatti that's worth more than a mil. There's a report out that the lawyer is taking aim at these goodies to satisfy the judgment. 

But Wayne sources say no one is going to sell any of Wayne's assets to satisfy any judgment, because he's worth as much as $100 million and can easily pay off the judgment.

It's interesting ... Wayne has thumbed his nose at everyone connected to the case -- So it's a little surprising Wayne is saying he'll pay the piper.
