Birdman and Lil Wayne's professional relationship continues to unravel. After hearing Weezy's new mixtape, 'Sorry 4 the Wait 2,' Baby is apparently fuming due to disrespectful lyrics about him and Cash Money Records.

The mixtape is full of lyrics that display Wayne's issues with his longtime label. On 'CoCo,' the Young Money leader raps: “I’m sorry for the wait… 'Tha Carter' gon’ be late so I cooked up a tape,” along with, “The garden’s full of snakes so I had to escape.” On the same song, he also blasts the notion that he's Birdman's mini me. “Birdman Jr? More like Ugly Duckling," he says. Ouch. He even compares signing to the label to doing a prison bid. “Did my time in Cash Money, time served and released / But this agent ain’t free, word, that’s the word on these streets," the New Orleans native rhymes.

These disses have made it to Birdman's ear -- at least we know he's listening to his artists' work. Sources tell TMZ that Birdman is mad that Wayne, whom he has publicly referred to as his "son" in the past, is treating him "like some random producer."

This is just the latest in a series of shots Wayne has fired against the label for apparently holding his album hostage. Last year, we reported that the rapper was threatening to sue Cash Money for failing to release 'Tha Carter V.' The album currently has no release date.
