Rob Kardashian My Family Didn't Know Jack About My Engagement

Rob Kardashian blindsided his family ... not giving them a heads up or even a hint about his engagement.

Sources familiar with the situation tell us, Rob went to great lengths to keep Kim and company in the dark. We're told the proposal was "aggressively on the QT."    

Our sources say Rob timed the proposal to go down when the family was away. The klan flew to Vail hours before he popped the question to Blac Chyna.

The women are not taking kindly to being squeezed out. They view the whole thing as "flaky" and, as we reported, none of the women jumped on social media to congratulate him.
