Lil Wayne continues to fight for his freedom from Cash Money Records.

Wayne has filed a lawsuit against Birdman and Cash Money, saying they violated his contract by withholding millions owed to him for his oft-delayed Tha Carter V album.

Weezy is suing for $51 million, according to TMZ. Sources tell TMZ that Carter V will see the light of day only if the rapper gets paid. He was promised an $8 million advance in December -- when he reportedly started recording the album -- and another $2 million after the album was completed.
