Lil Wayne is finally gonna tell the world if he really plans to make good on his threats to retire from music -- and it's all going down TODAY.
Weezy is all set to appear on "Undisputed" on FS1 -- where Skip Bayless will ask him straight-up if he's hanging up the mic for good ... as he hinted on social media earlier this month.
Of course, the legendary rapper has been at war with Birdman -- who he claims owes him millions of dollars and has been holding his never been released album, "Tha Carter V," hostage.
Wayne's been so pissed off over the situation, he's been following Drake from city to city -- where he's been jumping onstage and screaming, "F*** Cash Money."
But the real scare came when a clearly frustrated Weezy tweeted, "I am now defenseless and mentally defeated & I leave gracefully and thankful I luh my fanz but I'm dun."
Rap fans freaked out ... and huge stars begged him to reconsider ... and the next day, he sort of backpedaled.
But now we're finally gonna get our answer once and for all ... when Weezy sits down on "Undisputed" at 9:30 AM ET, 6:30 AM PT on Tuesday ... don't miss it.
