Kendall and Kylie Jenner
Kylie Jenner was "obsessed" with her sister Kendall when they were younger and used to follow her "everywhere".
Kylie used to follow her older sibling "everywhere" and the pair - who are the daughters of Kris and Bruce Jenner - were so close they even used to dress identically.
Speaking to Mexico's Marie Claire magazine, Kendall, 18, said: "She was obsessed with me. She followed me everywhere."
Kylie added: "If she got up in the middle of the night, I got up of the middle of the night. I literally couldn't leave her side. We even matched everything we wore."
Kendall - who made her debut at New York Fashion Week and London Fashion Week recently - admitted she has always wanted to be a model.
She said: "Even as a kid, I remember always looking at my mom's magazines, I would look up to them and I thought they were so beautiful and they seemed very elegant and cool.
"It's just something I really wanted to be."
Kylie is planning to pursue a career in fashion design but also wants to try her hand at acting.
She said: "Right now I love designing and I want to pursue that career once I turn 18. But acting is something I would regret not giving a chance when I'm older, so I would love to try it and see if I like it."
