Bruce Jenner and the Kardashians will open up about the star's gender transition in the first of a two-part KUWK special this evening.

Talking about the two part special, step-daughter Khloe Kardashian said: "It definitely is Bruce's story, but it's coming from a very... it's very raw, incredibly rough."
