Lil Wayne says he IS retired from music ... at least, for now ... and it's all over his war with Birdman.
The rapper just appeared on "Undisputed" on FS1 -- where Skip Bayless got straight to the point and asked if his tweets about retiring from music earlier this month were real.
The explanation ... Weezy says when he posted the tweet, he was PISSED OFF following a heated argument over his business relationship with Cash Money Records.
Wayne claims Birdman owes him millions -- and it's having a real impact on his personal life.
"I have a family. I have kids. I have a mother. We have bills. This is just business."
Wayne says he will NEVER work with Birdman ever again -- and for all intents and purposes, considers himself retired ... at least, until he gets paid.
He did send this message to his former boss -- "Gimme mine and I'll walk free."
It's clear Wayne WANTS to make music again -- because he told Skip he hasn't even come close to reaching the height of his career.
