Kendall Jenner Kim KardashianHold off on your assumptions -- it's not Kendall Jenner who wants to be just like big sister, Kim Kardashian, according to the second youngest of the Kardashian-Jenner empire, Kim is living vicariously through her.

The 15-year-old thinks that her big sis, who wanted to be a model when she was younger, is living through her own blossoming modeling career.

"Kim originally wanted to do runway but she was too short for it," Jenner says on a forthcoming episode of 'Keeping Up with the Kardashians' after having stormed out of a runway lesson her big sis had scheduled for her (via Us Weekly). "I think she's taking her fantasy out on me," she continued before screaming, "I feel like you're doing this for yourself!" at Kardashian.
