We reported earlier that Rob Kardashian got into it with his sisters, leaking Kylie's phone number in the process, after they planned a baby shower for him and his pregnant fiancée Blac Chyna — only thing is she wasn't invited. Now, it seems the reason they left her name off the invitation list has been revealed and it doesn't sound good for the couple.

According to TMZ, Rob's sisters actually planned separate his and hers showers because Rob and Chyna haven't been speaking for months. In fact, they reportedly only conveniently reunited for dinner the night before their reality show, Rob & Chyna, premiered.

Even though they reportedly haven't been communicating, Rob was still upset when he heard about how his sisters went about planning the shower, so he skipped it altogether and sought revenge instead. However, new details show that Chyna actually agreed that separate showers was a good idea but Rob wasn't filled in on that until after his social media blow up.
