However, it appears just to be a case of sibling rivalry! Kylie recently posted this sweet throwback, writing, "I just love this little cutie patootie." Sounds like this love-hate sisterly bond is going to be just fine.
Kylie and Kendall Jenner may be sisters, but that doesn’t mean they’re friends. Kylie, 20, opens up in the upcoming episode of Life Of Kylie about her relationship with her older sister.
“Kendall and I, I don't think we'd be friends if we weren't sisters,” the lip kit mogul confesses.
Jenner says she hates it when people assume she's jealous of Kendall’s modelling career. In fact, Kylie points out that she’s always happy to share with her sibling–unlike Kendall.
“I let her borrow whatever she wants. She always comes through and is like, 'I need an outfit please,' and I'll let her borrow whatever,” Kylie reveals.
“And then I go over there, and I'm like, 'Kendall, I need a pair of sweats to go home,' and she'll give me the most uncomfortable old underwear, the worst sweats you've ever seen and anything that's so bad and old and small,” she continued.
