The 44-year-old actor is a father of three, Trey, from his first marriage to Sheree Zampino, as well as Jaden and Willow, with his current partner, Jada Pinkett Smith, reported Daily Star.
His two youngest kids have followed him into showbiz, and Smith reveals they have almost complete control of their lives despite their tender years.
"We don't do punishment. The way that we deal with our kids is, they are responsible for their lives. Our concept is, as young as possible, give them as much control over their lives as possible and the concept of punishment, our experience has been - it has a little too much of a negative quality.
