The Kardashian-Jenner family is certainly no stranger to making big moves very publicly (just look at sis Kim K and her hubby, Kanye West, for a prime example). But now it’s the sole male sibling that’s hinting at some significant drama. Just days after announcing the sex of their baby, Rob K has erased all traces of Blac Chyna from his Instagram account. With a new Kardashian on the way — as well as a new show in the works — this is definitely a shocking move.

While Chyna’s Instagram account remains intact, she hasn’t posted a new pic since July 7, which is pretty darn abnormal for the lady who has joined the most social media savvy family in the biz and whose stream is FULL of selfies of her ever-growing belly.

But it’s the fact that Rob has made a major move with his Instagram account that has eyebrows raising. Not only has he deleted all pics of his fiancée (even the ones where he’s expressing his love for Chyna and their unborn baby), he’s gotten rid of ALL of his pics except for one: An old selfie of himself.

So what does it mean? Is there trouble brewing with the engaged couple? Is Rob just trying to get a fresh start? Or are they prepping for something HUGE?! We can only wait and see!
