Being the son of Hollywood major players Will Smith and Jada Pinkett Smith, 17-year-old rapper and actor Jaden was always likely to be a star. While still a young ‘un, Jaden starred alongside his pop in The Pursuit of Happyness and has gone on to have further movie success with a remake of The Karate Kid. The eccentric Jaden currently commands 5.75 million Twitter followers.

Aged just seven, she starred in I Am Legend alongside her dad and dropped her debut single “Whip My Hair” in 2010. Willow entertains an astonishing 3.7 million Twitter followers. Not bad for a 15-year-old.
