The series of uploads were Kylie's first since the drama unfolded over the weekend between her brother Rob and his ex-fiancé Blac Chyna, who is also the ex-fiancé of Kylie's current boyfriend Tyga. Just one month after Rob and Chyna welcomed their first daughter Dream together, the couple announced their split on social media. Immediately after their announcement, a hack on Blac Chyna's phone revealed messages that allegedly proved she was only dating Rob so she could cash in on the Kardashian name.
