Pittsburgh Steelers running back Le'Veon Bell is dead serious about his aspiring rap career -- telling TMZ Sports he's dropping a new track ... and says he's trying to collaborate with SNOOP!!
Bell raps under the alias "Juice" -- and recently dropped a 10 track mixtape called "The Interview" which already racked up more than 100,000 plays on SoundCloud.
But Bell says he's no 1-hit wonder -- insisting his upcoming track "On A Mission" might be his best one ever.
As for Snoop -- he's a HUGE Steelers fan ... and so is Mac Miller ... and Bell says he's trying his best to get those guys to hop on a track.
