Kim Kardashian was one of the first family members, if not THE first family member, to meet Caitlyn Jenner.

In this sneak peek from this week's Keeping Up With The Kardashians, Kim tells Khloe Kardashian what it was like when she first saw her on the set of her Vanity Fair shoot.

She tells Khloe, what all already know, that Cait is "really pretty" and she tells the camera that it was great seeing how at ease she seemed. "I was with Caitlyn at her Vanity Fair shoot. It was so good to see how comfortable she is in her own skin," she says in her confessional. "I'm so excited to see these pictures and to see the article, just for people to get to know Caitlyn."

After a brief discussion about pronouns, where Kim has to correct Khloe, who was admittedly having difficulty with the whole thing at the time, Kim reveals that she's even a little bit jealous of Cait's new...um, assets.

"So, then I went into the closet and she had to change. She was like: 'You can stay in.' And she took of her top and her boobs were like Kourtney's, like when she first got hers done," Kim recalled. "Like it made me want a boob job."

At the time, Khloe didn't even know that Cait had gotten implants, so that was a pretty big shock to her, but we're sure that once she saw how great - and HAPPY - Cait looks, she was just as excited for her as the rest of us are.
