In fact, the pair revealed, their older sisters are always on-hand to dispense advice, though each of them are helpful in different ways.
"If we're fighting, we call Khloe. She's our peacemaker," Kendall shared. "Kourtney keeps us down-to-earth." And Kim, whose baby-to-be with boyfriend Kanye West will soon join adorable cousins Mason, 2, and Penelope, 7 months, in the "next generation"?
"Kim teaches us how to deal with the spotlight," Kylie added. Even the men in the bustling household -- their brother Rob, 25, and sisters' respective boyfriends and husbands -- have an opinion when it comes to how Kendall and Kylie are growing up.
"Rob checks on me at least three times a day, and Lamar [Odom] wants to meet any guy we're talking to," Kylie said of Khloe's husband. "Just yesterday Scott [Disick] was going over the kind of guy I should date."
"Our family is closer because of the show. And when we are older, we'll have the memories on tape," she continued, about what life is like always being "on-set." "If some of those moments hadn’t been filmed, I wouldn't remember them!"
And the two teen entrepreneurs are making waves on their own independent of their famous older sisters. In addition to their respective modeling careers (Kendall signed with the Wilhelmina modeling agency at age 14, and both recently appeared in the ad campaign for prom and pageant dress designer Sherri Hill), the duo are set to launch their own clothing line with PacSun.
