Kourtney And Khloé Kardashian Reveal Which Sister Is The Messiest

When it comes down to it, the Kardashian sisters know each other better than anyone else.

Kourtney Kardashian is the oldest of the group, so you know she'll keep it real when it comes to her fam. She's not afraid to spill the dirt on her younger sisters and always tell it like it is.

This was proved on a recent episode of "The Ellen DeGeneres Show" when Ellen asked Khloé Kardashian to run the show for a day.

Khloé's first move as host was to FaceTime her big sis, Kourt.

The two girls briefly chatted and said hello to Khloé s live audience, but then they decided to play a game.

Khloé  listed off superlatives and Kourtney had to pick which sister fit the title best. SOUNDS LIKE FUN, RIGHT? Right.

In the next few minutes of the show, I learned more about the Kardashians than ever before. Thanks, Kourt. This was very educational.

Wanna know who the biggest troublemaker is? According to Kourt, it's Khloé.

Which sister complains the most? Kim, obviously.

Who's the messiest Kardashian? Kourtney didn't even have to hesitate for this one, she knew it was Kylie Jenner right away.

Damn Kylie, someone needs to clean their room! I guess when you have a wardrobe that huge, it's much harder to keep things tidy.

In the video above, you can watch Kourtney and Khloé Kardashian dish on how messy Kylie Jenner really is.  And as a special bonus, check out that time Ellen DeGeneres dressed up as the sixth Kardashian sister in the video below.

Let us never forget the beautiful Karla Kardashian. Always in our hearts.
