Kylie Jenner + Tyga + Blac Chyna
While Blac Chyna has never publicly said anything about it, the world knows that while she was temporarily playing BFF to Kim Kardashian, Kylie Jenner swooped in and started seeing her former fiancé and the father of her son, rapper Tyga. As the story goes, they broke up in 2015 after rumors of Tyga and Jenner’s relationship started popping up. In what was obvious retaliation, Chyna started dating Rob Kardashian in 2016, became engaged to him months later, and became pregnant, having daughter Dream in November. By early 2017, it was over between them.
