When Blueface isn't dealing with crazy baby mama drama, he's hitting the field with NFL stars to work on his game. 

The Los Angeles rapper, who was a high school football star who briefly played college ball at  Fayetteville State University,  recently linked up with Cleveland Browns superstar Odell Beckham Jr at UCLA to practice, and even Cam Newton made an appearance.

At one point, OBJ  offered to run a 40-50-yard route downfield and Blueface hit him perfectly in stride, which prompted Blueface to ask OBJ who had the best arm in the rap game.

OBJ admitted he had it, and the two swapped gloves. 

Peep the video below.
