Kylie Jenner And Her Sister Kendall Take Off Their Pants To Model Rob Kardashian’s Sock Line

Kylie Jenner, 15, and her sister Kendall Jenner, 17, help out their half-brother Rob Kardashian by modeling for his sock line, Arthur George. According to HollywoodLife.com, the two beautiful teens are often criticized for being too provocative for their age, but the girls seem to love modeling and are even photographed pantless at the Arthur George shoot.

In a photo shoot reminiscent of Tom Cruise in Risky Business, the girls posed only in pastel-colored button-up shirts and knee-high socks in gray and black. They sat with two other female models, leaning against each other and playing with their hair. In another shoot, Kylie posed seductively next to an also pantless male model.

Despite these teens looking a little too sexy for their age, their mother Kris Jenner couldn't be prouder. She posted a picture of the shoot on Instagram, with the caption: "Love this photo shoot for@Arthurgeorgesocks proud of you @Robkardashian"

Wetpaint.com reports that Rob's luxury sock line was once in danger, and Neiman Marcus almost cancelled their business deal with the line. However, the website is still running and advertising seems to be successful, especially with the help of his sisters.

In other news, Kylie Jenner was spotted cruising around in her $125,000 Mercedes-Benz G-Class SUV. According to The Huffington Post, the young teen took it out for a "spa day" at Spin Imaging in Long Beach, California.
