The unstoppable Kendall Jenner can now add columnist to her CV. The teenage model will be writing for WSJ. Magazine‘s February issue on the topic of youth. “I feel like I grew up too fast a long time ago,” Kendall writes. “Having older siblings, you grow up around adults, so you mature more quickly. I saw my sisters and parents working every day, so I was pretty much brought up to be a workaholic. But I just turned 19 a couple weeks ago, and I’m scared to be 20—it’s the first step out of being a teenager.” She also can’t quite imagine what her father, Bruce Jenner, was like as a teen. “I just laugh thinking about my dad being a teenager, partying. It’s the funniest thing. And it makes me think—what am I going to be like when I’m 65?” Jenner’s contribution in “The Columnists” puts her on a panel that also includes Tim Howard, Goldie Hawn, Jeffrey Jensen Arnett, Dr. Frederic Brandt and Maira Kalman, who all chime in on youth. The Feb issue of WSJ. hits stands on January 24th.
