Aww, sisterly love at its finest! Kendall Jenner, 20, may not let any one else mess with her sister, but that doesn’t mean she can’t take a jab at her. Kendall totally dissed little sis, Kylie Jenner, 18, after she posted this funny photo of Kylie’s questionable outfit on April 29. Don’t worry, there’s no drama here, just good ole sibling rivalry.
