The brewing feud between Kylie Jenner and Kendall Jenner is said to be caused by the 18-year-old Jenner wanting to copy her big sister.
Yahoo reported that Kendall Jenner is not happy that Kylie is now trying her luck in the world of modeling. The 18-year-old "Keeping Up with the Kardashians" star was recently featured in a Vogue magazine spread with Bella Hadid and Lottie Moss.
"I wouldn't be who I am today if it weren't for all my sisters," Kylie Jenner told Vogue.
It seems, though, that her closest sister, Kendall, is not so amused with her little sister's break in the fashion industry. "Kendall is supportive to an extent but there's always competition between these two," a source told HollywoodLife.com.
"If Kylie starts booking a lot of stuff it will become an issue. Modeling is Kendall's thing and it always has been. She doesn't love that Kylie suddenly wants to copy her."
Apparently, Kylie Jenner now sees a future for herself as a model. "Growing up it only seemed like Kendall had the goods to be a model, but Kylie is getting such positive feedback she's really considering it as a career possibility," the insider added.
The 18-year-old social media queen is open to more opportunities. Kris Jenner is said to have been working on getting Kylie into some shows for next season's fashion week.
Meanwhile, Kendall Jenner slammed her little sister on an episode of "Keeping Up with the Kardashians." E! News reported that the Victoria's Secret model got mad when Kylie brought Tyga along on their all-girls trip.
"I hate her so much sometimes," Kendall said to Kourtney when Kylie hung up on her and refused to answer her calls.
"Does anyone care that Kylie and T are just doin' the damn thing?" Khloe asked when she saw Kylie and Tyga. "She has to like make an effort to be with us."
"And bringing your boyfriend on a vacation is not making an effort at all to hang out with us," Kendall added.
