She had a nice little truce with Kylie Jenner going for a minute, but now it looks like Blac is back on the attack.

It's been months since Blac last threw Shade at Kylie on social media, but these days, Rob's baby mama is making up for lost time.

It all started when a makeup free photo of Kylie surfaced online, and Blac responded by posting this:

As usual, Blac kept the shade subtle, but it's there.

Many of her followers interpreted the stunned expression as a reaction to Kylie's bare-faced photo, and Blac did nothing to dissuade them of that notion.

Sometimes, that's all it takes to reignite the flames of a formerly white-hot feud.

The same day, Blac seemed to double down on her visual trash-talk by posting a photo in which she seemed to mimic Kylie's signature look:

Again, the comments section boiled over with lovers of drama, but this time, we think they were mistaken in their interpretation of shade.

These pics were posted before the latest pic of Kylie without makeup started making the rounds online, and we're pretty sure any similarity to Kylie was innocent and unintentional.

It seems Blac was just trying out a new look and fans dug a bit too deep in their search for beef.

Or maybe Blac is really just that committed to offering up the most subtle disses on Instagram.

We may never know for sure, as these two have kept things at cold war level - always at odds, but never publicly disparaging one another in ways they can't deny later.

At the end of the day, Kylie is still dating Blac's baby daddy, and Blac still has a kid with Kylie's brother.

Their lives are inextricably intertwined, and with their history it's unlikely that they'll ever be completely cool with one another.

So in all likelihood, the subtle shade will continue until the end of time.

Or until these two get desperate and E! offers them a reality show where run a small business together.

They'll still hate each other, but they'll either ne more overt about it, or they'll pretend to get along - whichever works better with test audiences.
