6. Jaden Smith, 16 ($8 Million)

At 16 years of age, Jaden Smith has a bank account that would make adults thrice his age jealous. Famous for the movies The Pursuit of Happyness and The Karate Kid, Jaden could be an A-list actor much like his father, Will Smith. Jaden entered show business at the age of five, with a number of appearances on the Smith-produced sitcom All of Us. He has made his film debut alongside his dad in 2006, and has become the highest-paid child star in Hollywood.
