Comedian and actor Paul Rodriguez hasn't worked with Will Smith since the 2001 biopic "Ali," in which Smith portrayed legendary boxer Muhammad Ali and Rodriguez had a small role as Dr. Ferdie Percheo — and there's a good reason for that.

"I'd never work with him again. He was an a—hole," Rodriguez tells  San Diego's Rock 105.3 during an interview. "There was no cause to insult me or berate me. I’m no angel, but I didn't have it coming this time."
