In the latest issue of Cosmopolitan Magazine (via Xpose) this week, Kendall opened up about how Kylie was initially "bothered" when she first started taking the catwalk by storm.

Kendall explained, "She's 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. I think that's a natural younger sister thing - to be jealous. I was jealous of her sometimes too!"

She added, "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?' It's as much a part of her life as it is mine.''

Kendall also opened up about her father Caitlyn Jenner's transition into a woman and how she always knew that she had an issue with his gender while they were growing up.

Kendall said, "With our dad, my sisters and I, we all had our experiences with it, but for Kylie and me, being the closest in age, we had our intimate moments of catching him or finding things. Those moments were me and Kylie only, so we had a different connection with it. My dad is my dad, he's their dad too, but he's my blood. I was Daddy's girl and was so obsessed with her - same as Kylie - we spent every day with my dad, so it had a special effect on both of us.''
