How Well Does Jonathan Cheban ACTUALLY Know The Kardashians?

We put him to the test with some Kardashian trivia.

He might not be a Kardashian by blood, but Jonathan Cheban is one of the few people who's had the privilege of keeping up with the sisters K without the barrier of a TV screen. founder has attended a handful of Kardashian nuptials, watched Kourtney serve up a meal of her own placenta, spent an afternoon sipping vino with Kris, and don't you dare claim he's leaked stories about Kim to the tabloids! 

With all these Kardashi-experiences under his belt, Cheban's a veritable trove of Kardash-info. But how well does he REALLY know Kris, Kourtney, Kim, Khloe, Kendall and Kylie? Watch HuffPost Live take him to task with some Kardashian trivia in the video above.
