No one knows you better than your siblings do. That probably explains why Kendall Jenner's impression of her little sister Kylie is so hilariously spot-on and savage at the same time. In a clip that appears to be a sneak peek from the upcoming season finale of Keeping Up With the Kardashians [1], the family decides to have some fun by dressing up as each other; Kris as Khloé, Kourtney as Kim, and Kendall as Kylie.

For Kendall's stint as her billionaire younger sibling, the supermodel throws on one of Kylie's many signature wigs in a pink ombré color, then puts on her best beauty guru face by testing out some of her Kylie Cosmetics [2] lipsticks. "Oh my god, it feels amazing on my skin," she says in her confessional while applying a bright red lip color all over her lips and teeth. "It feels so f*cking good." She even subtly roasts the way Kylie swatches her many shades by using one color named "One Wish" to doodle on her arm. Kylie obviously sees that it's all in good fun and compliments Kendall on her new look when she FaceTimes her a moment later.
