If this is Lou Williams' last year in the NBA, a big music career could be part of his retirement plan ... 'cause rapper 2KBABY tells TMZ Sports he's spent hours in the studio with the hooper -- and they have a bunch of songs ready to drop!!!
The 35-year-old Atlanta Hawks guard recently spoke out about his future in the league ... saying 2021-22 could very well be the last time we see Lou Will on the court.
Of course, Williams has dropped music in the past -- he even has a tribute track to the late Kobe Bryant -- but 2KBABY says there's much more on the way ... and he knows that because he's on the tracks!!!
"Shoutout Lou Williams, though," the "Luigi" rapper told us in L.A. this week. "That's my n****, bro. Me and Lou, we locked into the studio when I was in Atlanta."
"Me and Lou got some tracks."
Okay, so they have some songs together ... but is the 3-time 6th Man of the Year any good?!? 2KBABY says hell yeah -- "Lou can spit!!!"
2K even goes on to talk about how Lou Will compares to Damian Lillard's rap skills ... and you'll have to hear what he has to say!!!
