Jaden Smith blamed for ruining Bieber birthday bash

Jaden Smith has been blamed for ruining Justin Bieber's birthday party.

The 14-year-old actor - who is the son of Hollywood power couple Will Smith and Jada Pinkett-Smith - was allegedly responsible for the Canadian popstar and his entourage's confrontation with security that led to them having to leave a London nightclub on Friday night after just 15 minutes because they refused to let Jaden, who starred in 'The Karate Kid' remake, into the event because he is underage.
