Cam Newton's off-season is LITTTT!!!! ... 'cause the Carolina Panthers QB celebrated his new sneaker release by spittin' bars with 2 Chainz!!
Cam grabbed the mic and put his rap skills to the test while goin' bar-for-bar with Tity Boi to perform "Riverdale Road" at the Under Armour event Thursday ... and we gotta admit, the dude's pretty impressive.
It shouldn't come as a surprise that the Pro Bowler decided to rock a Mad Hatter-esque look for the event ... 'cause Cam's known for makin' fashion statements.
