Kendall Jenner departed from Los Angeles International Airport on Thursday, and she's heading to France to join sister Kylie and Kim, along with mom Kris Jenner. Party time! Or at least group selfie time...

When she's not walking the runway, shooting ads or vacationing with her girlfriends, Kendall is spending time with her family, and she recently revealed that the gym has taken a bit of a backseat. Seeing as she's 19 and super fit to begin with, you'd never know, but she told People, "I haven't worked out in a month. I've been too busy. I live on a plane. I'm really trying to balance work, family and friends. The other day I was supposed to have a fitting, and I moved it back and hour so I could take a nap."

Still, she's grateful for the time she has with her sisters -- and for the advice they give her! “Kylie and I got very lucky because our sisters are years older than us," she told People. "They made their beauty mistakes and then warned us. Kylie and I were both really little, and we were sitting by the pool. I think we were touching each other’s faces, and my sisters were like, ‘Never touch your face! Never! You don’t want pimples.’ They told us to always keep our faces clean."

Wonder what kind of relationship advice Kim, Khloe and Kourtney have for their teenage siblings though? We'd love to hear that!
