Sources say, Rob Kardashian blindsided his family when he didn't even give them a hint about his engagement to Blac Chyna. 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 reportedly not taking kindly to being squeezed out. None of the women jumped on social media to congratulate him.
