Kylie Jenner, 23, had the cutest “helper” in the kitchen: Stormi Webster! The Kylie Cosmetics founder and her two-year-old daughter made Halloween cookies for a YouTube video posted on Oct. 5, which served as proof that Kylie and Stormi make the cutest team ever. “Are you going to be a good helper?,” Kylie asked her little one in the beginning of the video, and Stormi replied, “Yes mommy.”
