While it may be true that Kylie Jenner's star is rising and Kim Kardashian's is falling (especially among younger fans), the tabloid world is abuzz with rumors of a feud over Kylie's new relationship with rapper Tyga. Kim is unhappy, not because Kylie is 17 and Tyga is 24, but because Kim is friends with Blac Chyna, a 26-year-old model and the mother of Tyga's son, King Cairo Stephenson (at least he starts with a K). Obviously, it is SO AGAINST THE RULES to date the baby daddy of a friend of your half-sister, who at 34 is literally twice your age. How did proof of this feud reach the world outside of the Kardashian-Jenner empire? Well, Tyga and the Kardashians were all present at a birthday party for rapper French Montana, but when Kim posted a group photo from the evening, she cropped Tyga out of it, even though he was standing right next to her. That's cold on another level. —JMC
