The teenage reality stars took the time for the game while speaking to the mag about their new Kendall + Kylie collection for Topshop. Kendall, 19, rocked a pair of $58 floral shorts with a matching $68 floral shirt for the shoot, while Kylie, 17, chose a $105 jumpsuit with cutouts from the line.
The Jenners accessorized their warm weather wear with sparkly paddles for the game, flipping the tools back and forth to read "Kendall" or "Kylie" depending on the question.
Kendall and Kylie disagreed on many things, including which of them takes the most selfies as each star chose her sister. The two were, however, able to agree that Kendall is the bigger tattletale, the better secret-keeper, and eats more junk food, but she added, "But I'm better now! I got really good."
Kylie may be famously active on Instagram, but the youngest of the Kardashian-Jenner clan revealed when asked about the sisters' emoji use that she's "not a big texter."
In one particularly heated moment, both Kendall and Kylie flipped to their own names when asked which sister is nicer. "Kylie, stop, you can be honest!" Kendall said. "No! You're my biggest bully in life ever," Kylie shot back to her older sister.
The two stars went on to touch on their past as cheerleaders, arguing over whose position on the squad was harder. To prove their cheer prowess, they even did a coordinated routine, with Kylie putting her sister to shame in the end.
