That’s gotta hurt! Kylie Jenner reacts to Blac Chyna’s emoji app dis (you know, the Chymoji that features a Kylie look-alike avatar being slapped in the face) in a preview for the Sunday, August 14, episode of Keeping Up With the Kardashians.

In the clip above, Jenner’s older half sister Khloé Kardashian asks the Lip Kit queen, 18, whether she is angry over Chyna’s shady social media move. “Aren’t you upset that Chyna made an emoji about you?” the Strong Looks Better Naked author, 32, says.

Next, Kourtney Kardashian offers her take on the situation: “Just when everybody was welcoming Chyna into the family, this comes out," the 37-year-old mom of three says during a confessional.

Though the Kylie Cosmetics founder and Chyna, 28, made up in April, the former video vixen — who is pregnant and expecting a baby girl with Jenner’s half brother, Rob Kardashianreleased her Chymoji app in May.

“There’s so much misunderstanding going on,” the youngest of the Kardashian-Jenner clan woefully tells the camera.

As previously reported, Jenner and Chyna seemingly put their differences aside this past spring when the former enemies took to Snapchat to document a memorable hangout session. The KUWTK star even referred to Chyna, who shares son King Cairo, 3, with her ex-fiancé and Jenner’s current beau, Tyga, as her “best friend.”

“When we’ve been best friends the whole time,” the makeup maven wrote on April 21, accompanied by a mirror pic of herself and Chyna. The Rob & Chyna starlet — who accepted a proposal from the sole male Kardashian, 29, back in April — also shared a hilarious face-swap with Jenner and wrote: “Hanging out with my lil sis.”

Watch the video above. Keeping Up With the Kardashians airs on E! Sundays at 9 p.m. ET.
