Kylie Jenner isn't the only one with a grill, her sister has one too! In a new Instagram photo, Khloé Kardashian is showing off her grill. Back in Dec. 2014, Jenner gave Instagram followers a look at her grill and now, her older half-sister is putting her own on display. So the main question now is, who works their grill the best: Kylie or Khloe.
