"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," 19-year-old Kendall says of her younger sister. "I think that's a natural younger-sister thing, to be jealous. I was jealous of her at times too!"

But while the minor sibling rivalry may have reached a high when Kendall's work picked up, it seems like the sisters have managed to squash any beefs and now show nothing but support.

"Now she loves what I do and supports me," Kendall says. "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 as it is mine."

Wow, good to know Kylie is okay now.
