Will Smith's son Jaden is reportedly dating reality star Kylie Jenner.

Us Weekly reports that the 14-year-old Karate Kid actor has been 'recently romancing' the 15-year-old Keeping Up With the Kardashians star.

The young couple were spotted enjoying a lunch date at Caffe Nero in London at the weekend.

"They''re dating," a source told the publication.

Kylie has previously been linked to Australian pop star Cody Simpson, but denied the reports last year saying that they’re good friends.
