Jaden Smith Dating Kylie Jenner

Will Smith's son and Kim Kardashian's half-sister spotted together in London

Young love is in the air! Jaden Smith, 14, is reportedly dating Kim Kardashian's half-sister Kylie Jenner, 15, a source close to the new couple reveals to Us Weekly.

The Karate Kid star, son of Will Smith and Jada Pinkett Smith, and the reality starlet have reportedly been "friends forever," but are now taking their friendship to the next level. "They're dating," the source confirms.

The pair were recently spotted dining together in London, where Smith was attending Justin Bieber's birthday party. The party was cut short, however, when Bieber's entourage got into an argument with club security over some of the "Boyfriend" singer's underage guests, including Smith.
