Rob Kardashian, 27, took #WomenCrushWednesday to wholly inappropriate new heights when he took to Twitter to pay homage to sister Khloe's bum.
Yes, really.
He tweeted a picture, featuring Khloe, 30, and her infamous legging-clad derrière, as seen from behind.
He then hilariously captioned the pic: “#WCW @khloekardashian shneeeeee meeeee claaaaaa.”
Unsurprisingly, plenty of people responded with the phrase: "Dude, that's your sister!"
Khloe, on the other hand, decided to accept the compliment and get in on the joke, teasing her brother with a suitable sassy response.
“Totally a normal brother/sister relationship. Incest is best!!! #HeyBooHey,” she wrote on Instagram with a screenshot of her brother’s post.

Rob and Khloe have been motivating each other to work out and eat healthy,with a source revealing to E! News exclusively that Rob's "taking it slow [and] feeling great."
The insider added: "Rob and Khloé have always been tight.
"And Khloé has been there 100 percent for Rob since he's been going through hard times... Khloé... is probably closer with him than any of her sisters."
It's good to see these two are still so close, isn't it?
