Of everyone who’s beefed with the Jenner sisters, Blac Chyna has the most valid and understandable reason to dislike Kylie: Tyga was engaged to Chyna when he began allegedly dating a then-underage Kylie.
Even Kylie’s own sister, Kim Kardashian, wasn’t happy about Kylie’s romance with Tyga, saying on an episode of Keeping up with the Kardashians (via Us Weekly): “I understand that Kylie dating Tyga completely broke Chyna’s heart. I feel for her in that situation. Was it uncomfortable for me when Kylie and Tyga started to date? Absolutely, because Chyna was my friend.”
There has been plenty of vitriol and pettiness back and forth on social media between Chyna and Kylie. In 2015, TMZ reported that Chyna mocked Kylie’s lip injections and that the women feuded over watches Tyga gifted them. In 2016, Entertainment Tonight reported that Chyna accused Kylie of copying her idea for an online cooking show.
Tensions seemed to cool at least somewhat when Chyna got engaged to Rob Kardashian in 2016, but that didn’t end well either. In October 2016, Chyna accused Kylie of copying her birthday party theme for Chyna and Tyga’s son, King Cairo.
In September 2017, The Blast reported that Kylie sued Chyna for vandalism for destroying Kylie’s property when she lived in Kylie’s house with Rob and Dream. Just a few weeks later, People reported that Chyna sued Kylie, Kendall, and the rest of the Kardashian krew for allegedly damaging her brand.
