Lonzo Ball just shaded the hell outta his old NBA team for trading him this off-season ... and also went after his ex-business partner, Alan Foster in the process.
It's clear Zo is motivated by the blockbuster trade that sent him packing for NOLA in exchange for superstar Anthony Davis -- spittin' "You know I'm all about business ... L.A. is gonna regret their decision" in the hook of his song, "Last Days."
But the Lakers aren't the only target in his song ... he also mentions his old family friend Foster, who he's currently suing for allegedly stealing MILLIONS from the family's Big Baller Brand.
