For his #WomanCrushWednesday, the reality star and sock designer tweeted out a photo of his older sister wearing a pair of slightly see-through legging, writing:
— ROBERT KARDASHIAN (@robkardashian) October 1, 2014
Khloe, presumably flatter and perhaps slightly creeped out, mocked her brother’s odd choice in celebrity crushes, writing back in an Instagram screenshot of his tweet, “Totally a normal brother/sister relationship. Incest is best!!! #HeyBooHey.”
However, this wasn’t the first time the Keeping Up With the Kardashians twosome joked about their close relationship. While guest-hosting an episode of Chelsea Lately earlier this year, Khloe made a crack at having sex with her younger sibling now that he was living at her house.
“You may know me as the only Kardashian sister that Chelsea [Handler] actually likes. However, most people know me as the sister of fashion icon and sock tycoon Rob Kardashian,” she said. “Rob’s been on my mind a lot lately because we’re currently living together. And no, we’re not sexually involved — my brother’s not nearly black enough for me!”
