Rob Kardashian Posts Khloe’s Booty Pic, She Says ‘Incest Is Best’

Keeping Up With the Kardashians star Khloe Kardashian seems to have a rather questionable relationship with her brother. On Wednesday, Rob Kardashian tweeted out a pic of Khloe’s famous booty and dubbed her his Women Crush Wednesday (WCW).

If the photo didn’t raise raise eyebrows, Khloe’s “Incest is best” response certainly did, with many fans wondering how close the siblings really are.

The photo Rob posted on Twitter is actually a screenshot of a picture that was originally posted on the KUWTKGirls Instagram account. The two-pic photo collage shows the reality star stepping out of her car and then heading into a Beverly Hills gym, giving the photographer a clear view of her famous backside.

Khloe loved the fact that her brother gave her “WCW” status, sending back immediate approval via Instagram, with the caption, “Totally a normal brother/sister relationship. Incest is best!!! #HeyBooHey.”
