Kim Kardashian grills Khloe over getting secret Botox: 'Your whole face has changed'

Nothing is necessarily real when it comes to the Kardashians, but apparently the sisters still haven't received that memo.

Kim Kardashian grills her sister Khloe about whether she's had work done in the latest teaser for Keeping Up with the Kardashians - and Mrs West clearly doesn't approve.

Erm, has she looked in the mirror lately?

Watch the clip above to see Kim, 35, pestering Khloe, 31, over her recent change in appearance. It makes us wonder if she's ever heard any of the talk about little sister Kylie's ever-changing face…or her own.
