Khloe Kardashian has proved that siblings could easily win a gold medal if teasing was an Olympic sport in a new teaser for the mid-season finale of Keeping Up With The Kardashians.

Choosing honesty as the best policy (because obviously), Khloe gave sister Kim Kardashian her true thoughts onher outfit choice in the teaser on E!, hinting that she looks like a, erm, hooker.

Aww, sisterly love.

Kim got the surprise reaction when she debuted her LBD (teamed with a choker necklace and her hair in a top knot)whileKhloe was having a conversation with brother Rob.

Reacting to seeing her sister’s outfit of the day, Khloe said: “Oh my – you've got to get out of here.”

With Kim asking 'what?' and Rob laughing, Khloe then joked: “Kimberly – how much are you?!”

Admitting that she did have her reservations about the dress, Kim explained: “I know, the neighbour did kind of look at me like: 'Hooker city’. I did feel uncomfortable for one second.”

Khloe continued with her honest review, adding: “You literally look like Rob paid for you. I literally just dropped my jaw when I saw you. Wow.”

After Kim told her siblings to ‘chillax’, Rob reassured her that their reactions weren’t bad ones, saying: “It wasn't a bad ‘wow’.”

Siblings, eh?
