Kylie Jenner vs. Blac Chyna
The drama between Kylie and Blac can be boiled down to one person: Tyga. The "Stimulated" rapper was once engaged to Blac, but he dumped her for a then-underage Kylie in 2014. Soon afterwards, both women began trading thinly veiled insults on social media. Kylie posted a photo of herself wearing an Audemar Piguet watch on Instagram — which happens to be identical to a watch Tyga once gave Blac — and Blac returned fire with multiple #tbt shots of her getting up close and personal with the "Stimulated" rapper, and a picture mocking Kylie's controversial lips. More heated tweets and Instagrams followed, to the point where Amber Rose and Khloé Kardashian got involved, and started their own feud.
