Lil Wayne's diss-heavy Sorry 4 the Wait 2 mixtape was just a warm up. Weezy is now suing Cash Money Records and co-CEO Bryan "Birdman" Williams for a gigantic $51 million.

Lil Wayne has filed a breach of lawsuit contract against Cash Money. In the suit, Wayne (or Dwayne Michael Carter, Jr. as he's referred to in the legal realm) claims that the label never paid for his upcoming (retirement?) album Tha Carter V. The suit cites disputes with the label for delaying Carter V months after its intended May 2014 release date, alleging that Wayne was prohibited from auditing the label's records. It's all the more heartbreaking when you consider that Birdman—who's been like a father to Wayne for nearly two decades—appears to be instrumental in what Wayne referred to in December as an imprisonment of creativity.

Here's what Weezy wants now: The $8 million he was owed when he began recording his new solo album and the $2 million when he finished it—guaranteed to him from his Cash Money Records deal, according to the suit. Wayne says Cash Money only paid $2 million, didn't provide a quarterly $200,000 fee of overhead payments, nor gave him his royalties from his and Drake's recent albums. All that comes together for a quick and easy payment of $51 million, Wayne's lawyers claim.

The "Amazing Amy" MC has also requested to be declared a joint copyright holder on everything released on Young Money Records, Tunechi's imprint of Cash Money, which includes Drake and Nicki Minaj material.

What it boils down to is, because Cash Money has not paid Lil Wayne the money he's owed, he should be able to leave the label. 

Despite Weezy making his unhappiness clearer than ever, Birdman still has to comment on the matter. Back in December, after the heated series of tweets, Wayne's manager made it sound like everything between Wayne and Cash Money was totally A-OK.
