Kendall and Kylie Jenner had a heated argument before Caitlyn Jenner's ESPY award ceremony this summer. It resulted in several sisterly insults being tossed around. The video is a look at the premiere of season 11 for Keeping Up With The Kardashians. The trouble begins as they were getting ready for the ESPYs at Kylie's house. Somehow, despite much of Kendall's career revolving around clothing and fashion, she did not have anything to wear. Additionally, this was prior to Caitlyn Jenner's very public and very important acceptance of the Arthur Ashe Courage Award.
