I got a motto - my motto is - whatever you do to her, I'm going to do to you." He also revealed how he is currently making a movie about his experiences in the band NWA, and how he has his son eyed up to play him. "I got one role in mind that I hope that my son lands - I hope he plays me in the movie. I think he could do it, so we'll see. He definitely looks close to what I looked like back at 17/18." He went onto discuss how his son is following in his rapping footsteps, although the subject of his songs are somewhat different.
