Kendall Jenner revealed that she and younger sibling Kylie Jenner were jealous of each other. Kylie was annoyed with the attention Kendall received because of her modeling career, Kendall said, in an interview with Cosmopolitan.

“She’s [Kylie] a Leo so she loves attention, and at certain points when we were younger, it bothered her that I was getting attention in terms of my modeling,” Kendall told Cosmopolitan in the magazine's latest issue.

The 19-year-old also said that Kylie made her jealous too. “I think that’s a natural younger sister thing-- to be jealous,” she said. “I was jealous of her sometimes too! But now she loves what I do and supports me. She’s very into fashion and always texts me when I’m doing a big show like, ‘That is the sickest thing ever! How were the clothes?'” Kendall said. “It’s as much a part of her life as it is mine.”

Recently, it was reported that 18-year-old Kylie’s freedom to experiment with her hair made Kendall envy her younger sister.

“She can go blue for a while, blonde, put it in cornrows, dreadlocks and cut it however she likes, a source reportedly said, adding: "Kendall has been told that designers and advertisers really like her long straight black hair and that she shouldn’t mess with it. She won’t get the top notch modeling jobs if she has bleached or blue hair."
