Kim Kardashian is reportedly wary that Kendall will become a bigger fashion star than her.
The Keeping Up with the Kardashians star has allegedly been trying to get in with style bigwigs and is close to high-end designers such as Riccardo Tisci.
But 18-year-old Kendall, Kim's half-sister, is already a firm favourite with major industry players. She recently walked for Marc Jacobs at New York Fashion Week and for Giles Deacon at his London show.
"Kim loves how famous she and Kanye [West, her fiancé] are. But there's a worry in the back of her mind that her fame will start waning. And now Kendall's coming right up behind her and being offered magazine covers. Kim's very precious about being upstaged by anyone, so Kendall's rising fame isn't going down well," a source revealed to Britain's Now magazine.
"Kendall and Kim are so different physically. Kim's often wished she has what Kendall has - looks are very important to her."
To make matter worse Kim, 33, doesn't always feel she belongs in the world of high end fashion, says the source.
Despite this, she tries hard with her style choices and has overhauled her entire wardrobe in recent years.
"Kim still doesn't feel comfortable in that world. She feels like an outsider no matter how hard she tries. She believes that she's invited to fashion shows just because of Kanye, who's well respected by designers and fashion journalists.
"Kim devotes a lot of time into putting the right outfits together and being seen in the right labels," the source added.
Friends close to the TV personality have laughed of rumours that Kim is envious of her younger sister, and say all she wants is for Kendall to be happy.
"Kendall's still very young and vulnerable. Kim just worries that the fame will be overwhelming to her," an insider explained.
