Birdman is angry at Lil Wayne for "disrespecting" him in his latest song ... and he will NOT voluntarily release the rapper from Cash Money ... sources connected with the mogul tell TMZ.
Our sources say Birdman is angry on 2 fronts ... that Wayne is trying to bail on a binding contract and even more personal, he's putting their relationship on blast.
Wayne's song, "I'm Sorry for the Wait," is especially galling to Birdman because he feels the man he calls "son" is treating him like some random producer.
As we reported, lawyers and others for Wayne and Birdman are in talks, but Wayne has threatened a lawsuit if his album isn't released.
Our Birdman sources say the mogul won't budge and will only release the album on his terms. And he will fight Wayne if he sues to get out of his contract.
