So it makes sense that there might be a little bit of a sister rivalry going on between the two. Especially considering they're in the same industry. In Kylie Jenner's latest YouTube video, she applied her big sister's makeup, and the two jokingly competed and dissed each another's companies.
Some fans noticed that Kardashian totally shaded Jenner's product on camera, but at the end of the day, there's nothing but love and support between these two sisters.
Kylie Jenner worked as her big sister Kim Kardashian's makeup artist in a new Youtube video.
Kardashian rarely lets anyone, besides her longtime makeup artist Mario Dedivanovic, do her makeup. So it was very special that Kylie Jenner got to do her own signature glam on her notoriously picky sister. In the video they answered some fan questions and got a bit competitive with one another, though in a totally joking way.
