Atlanta Hawks superfan 2 Chainz says he's ready to move from courtside seats to the OWNER'S BOX -- telling TMZ Sports he's "definitely interested" in buying a stake in the team.
2 Chainz joined the guys on "TMZ Sports" on FS1 -- and said he loves the deal Usher made to become a minority owner of the Cleveland Cavs ... and says he'd love to follow suit in ATL.
"If it happens it happens," 2 Chainz said ... "but I'm definitely interested."
"It would be exciting to get a percentage, get my own parking space ... you know, live it up."
Ya gotta watch the show -- 2 Chainz (a former college basketball player) also challenges another rap superstar to some 1-on-1 ... and it's pretty hilarious.
Make sure to watch "TMZ Sports" weeknights at 9 PM PT, 12 AM ET on FS1.
