Rob Kardashian admits to once having a crush on his sister!

We all knew that the Kardashians were a close family, but we had no idea they were THIS close!

In a new episode of his reality show, Rob Kardashian reveals that he once had a crush on one of his sisters.

Blac Chyna was the one to actually say it, and Rob confirmed it.

When asked who his childhood crushes were, she replied: "J-Lo and Kim Kardashian" to which he weirdly replied: "That is also pretty accurate."

And as if that wasn't weird enough, she then also added, "these are facts."

THIS IS SO WEIRD. WHAT THE ACTUAL F.
