Rob Kardashian Might Be Hooking Up With His Sister's Nemesis Blac Chyna

Brace yourselves!

Can you say drama? 

On Monday, Blac Chyna shared a photo of herself in the arms of a tattooed man, whom we are 99.9 percent sure is Rob Kardashian. 

The beginning ☘

The 27-year-old old model captioned the Instagram snap, "The Beginning" -- yeah, the beginning of a lot of drama. 

For the uninitiated, the pairing is downright crazy considering all of Blac Chyna's history with the Kardashian family. 

You see, way back in 2013 and 2014, Rob's sister Kim was pretty close with the model. They took pole dancing lessons together.

They celebrated birthdays together.

But most of that was before the model split from then fiancee Tyga, with whom she shares a a 3-year-old son, in August 2014. That was certainly before Kim and Rob's youngest sister, Kylie Jenner, was rumored to have started dating Tyga a few months later (the couple went public with their relationship in August 2015, once Jenner turned 18). 

You better believe that pairing didn't sit well with Blac Chyna -- thus igniting a feud between the model and the teen reality star that played out on Instagram and Twitter, with the model notably taking aim at Jenner's much-buzzed about lips.

And while the feud between the two seems to have quieted in recent months, it's certainly not over. We can only imagine what must be going on at Kardashian headquarters with the news that Rob might have crossed over into enemy lines. 

In fact, shortly after Blac Chyna shared the photo in question, Rob's sister Khloe tweeted:

And while she first quickly denied the tweet was about Rob, she followed it up by acknowledging that while it wasn't her initial intent, she might as well have been talking about him, too.
