How vague can u get?
Anywayz, I doubt anybody knows the complete details on how Chris & Pac met. I doubt many would care. But my guess is that since Dr. Dre and Ice Cube once again cool at the time and Ice Cube and Chris Tucker had just did a movie together, Ice probably introduced Chris to Dr, Pac and Troutman, since Ice did do songs with each of em. That's as far as anybody will get i think
