Kourtney Kardashian may be Khloe's favorite sister ... but the 28-year-old is our favorite Kardashian!

The "X Factor" host sat down with Andy Cohen on "Watch What Happens Live," where she played "Not Plead the Fifth" with the Bravo host -- meaning this time, she had to answer all the questions.

Andy took full advantage of the game, asking Khloe which of her sisters' boyfriends she'd rather "bone," Scott Disick or Kanye West.

He also made her rank her siblings in order from favorite to least favorite.

Check out the video above to see if she'd prefer Kim or Kourtney's beau in bed ... and which of her famous family members she likes the least (her answers will probably surprise you!).
