The 18-year-old model said Kylie, 17, is the messiest person she has ever met, who can even be disrespectful towards other people's stuff at time, reported Female First.
"She's (Kylie's) really dirty. She's the messiest person ever and does not care. Literally she'll sleep at my house for one night and I'll go into the guestroom and it'll be trashed," Kendall said.
