The Kardashians who have been silent over the epic engagement all this while, might be doing so more from speechlessness than creating any drama.

Rob shared the video of Kim crying with the caption:

“Had to post this snap my sis sent me. LOL she’s got jokes! #KimsCryFace.”

In the video, Kim who looked as serious as one possibly can with fake tears hanging from their eyelids, said, "Rob, we really need to talk", just before the tears come flooding out.

Rob shared another video of Kim, in which she is seen rocking an animated L.A Dodgers cap, as she says, "In honour of Rob's big day," with the caption, "Sister Love."

Although the videos suggest that Rob and his family might actually be on good terms, the Kardashians are yet to make any formal statement concerning the engagement.

However, a source has reportedly revealed to Us Weekly, that momager, Kris Jenner and the rest of the Kardashian clan, are convinced that he is 'making a mistake' by rushing into an engagement with the mother-of-one, but Kris is willing to pretend that she is happy.
