We kick off our look at the sons and daughters of Hollywood actors with Jaden Smith, who may well be the very definition of Hollywood royalty. 11-year-old Jaden is the son of Will Smith and his wife Jada Pinkett and he looks set to make a splash this year starring in the title role of the Karate Kid remake (opposite none other than Jackie Chan). The boy is already something of an old hand: he played his father's son in The Pursuit of Happyness and starred with Keanu Reeves in The Day The Earth Stood Still, as well as presenting an award at this year's Oscars. Not content with just acting, Jaden also raps and dances, and future film projects include the big budget actioner Amulet, due for release in 2012.
