You know how Rob Kardashian and Blac Chyna are engaged and about to have a baby together?
And there was all of that, umm, awkwardness between them and the rest of the Kardashian family members?
The short version: Blac Chyna was once engaged to Tyga and they had a baby together. At the same time, Chyna was super close to the Kardashians, Kim being one of her closer friends. Then Chyna and Tyga broke up, Tyga started dating Kylie Jenner, Chyna distanced herself from the Kardashian fam, and a bitter feud began. THEN Rob Kardashian started dating Blac Chyna, they got pregnant and engaged, and the rest is history.
