It's been a long and bumpy road to healing for Blac Chyna and Kylie Jenner, once mortal Instagram enemies and now-impending sisters-in-law — but it looks like an emoji could end up being a speed-bump in that road.

Following in the footsteps of Kim Kardashian and Amber Rose before her, Blac Chyna released her own line of emojis, ChyMojis, back in May. While the series features mostly semi-creepy illustrations of her and her beau, Rob, one in particular had the Internet talking: an animated emoji of a girl who looks almost identical to Kylie getting slapped across the face.

In a new promo trailer for an upcoming episode of Keeping Up With the Kardashians set to air Sunday, August 21, the famed E! reality TV family — Kylie included — reacts to the seeming emoji diss.

"Aren't you upset that Chyna made an emoji about you?" Khloe asks Kylie in the clip.

In her confessional, Kourtney seems equally aggravated, expressing, "Just when everything was welcoming Chyna into the family, this comes out."

However, the Kylie Cosmetics mogul doesn't appear as upset, saying in an aside, "There's so much misunderstanding going on."

Meanwhile, there seems to be trouble in paradise for camera-shy Rob and his model/entrepreneur wife-to-be. According to tabloid reports, the couple is reportedly going through a rough patch as they struggle to film their own reality show spinoff, Rob & Chyna.
