Although reports that Justin Bieber and Kim Kardashian were a couple surfaced recently, it seems he is dating another Kardashian. Justin Bieber is dating Kim’s little sister Kendall Jenner who is more his age, 14.The two have been together for a while and Kim is around alot because the sisters are very close. I’m sure it’s also to cover up the relationship from the media a little too since she is so young.
