Kendall & Kylie Play 'Which Sister' With 'Glamour'

When I was growing up it was almost impossible to step into any toy or department store without spotting some Olsen twin memorabilia; now Kendall and Kylie Jenner have taken on the title of Hollywood‘s “It” sisters. The girls launched their second clothing line Kendall + Kylie for Topshop last week, and during a behind-the-scenes look at their photo shoot with Glamour magazine, Kendall and Kylie Jenner played "Which Sister,"answering a series of questions that gave us a taste of each young woman's personality.

Celebs oftentimes lead two lives: off-camera, when they're clad in "sweat pants, hair tied, chillin’ with no makeup on" like the rest of us once we're off the clock, and the persona they portray for the public and the paparazzi. Reality stars are different; their lives are the camera.

So while Kendall and Kylie were asked who was more likely to do so-and-so, I played along, and answered the majority of questions correctly. Say what you want about the Kardashian-Jenner clan, but they are who they are, camera or no camera.

Sisters will be sisters, and though they may look alike, Kendall and Kylie are far from one and the same. I've highlighted my favorite moments from the Jenner's round of "Which Sister?" but be sure to check out the full video below and find out for yourself just how well you know Kendall and Kylie. I'm willing to bet you know them better than you'd think.
