Kylie proved that she's the more wild Jenner sister after she was filmed giving Kendall a lap dance in a Vine video. The 17-year-old reality star wildly gyrated around to the New Boyz hit song "FM$," and at the end she made it twerk on her older sister. 

Speaking more about family, Kylie recently did an interview with Miss Vogue, where she opened up about her family's dynamic. She admits to bumping heads with older sister Kim, but says her family always works as a group to help one another succeed. 

"[Kim and I] butt heads ... but in a sisterly manner. We like to succeed as a group, so we are never really jealous. We don't want each other to fail."
