"I'm closest to Kendall, I spent every second with her growing up," the 17-year-old told Grazia. "After that it's probably Khloe."
It sounds like her relationship with Khloe is a little different, though. "Khloe is more of a mom to me than my mom is sometimes," she explained. "My mom is all about being best friends."
This isn't the first time Kylie has given Khloe a shoutout for playing a motherly role in her life. In January of this year, Khloe posted a quote from Kylie that read, "Kylie on Khloe: She has always been the strictest on me - taking away my cell phone, having my passwords to everything." Along with the photo, Khlo wrote, "I'll always be your mommy sister @kyliejenner LOL you are my heart."
