There are those who are wondering what the fuck this means for the Kardashian tree ( we got you ) and there are those who are being petty and trolling Kylie Jenner's and Tyga's Instagrams.This happened before, when Rob and Blac Chyna announced that they were engaged . The comment section on his Instagram feed was flooded with diamond-ring emojis and shamrocks, which has come to represent Rob. And now it's happening again.But this time, it's all baby faces and bottle emojis.
