Just like any brother and sister, Rob Kardashian and Kylie Jenner have had their share of fights—except their bickering has played out in the public eye.
In the latest installment of their fluctuating drama, the reality star and sock designer shared his youngest sister's real cell phone number as a ploy to get back at her. For what? It seems they were arguing after his pregnant fiancée, Blac Chyna, was not invited to a baby shower the Kardashians were holding in his honor.
"Didn't invite the Mother of my child to a baby shower you all were trying to throw for me ? You all must have lost your damn minds," he wrote after sharing Jenner's digits and clarifying his account had not been hacked.
According to a source, Rob couldn't make it to the "DILF" party planned in his honor and that's where the bickering began. "Rob couldn't attend, so Chyna was going to attend and Kim [Kardashian] said if Rob didn't go, then Chyna couldn't go. It sounds like that's what caused the argument."
While Jenner has since changed her number, their ongoing beef is far from new and sparked as a result of Rob's personal connection to Chyna.
As is common Kardashian knowledge by now, Kylie's longtime boyfriend, Tyga, was previously engaged to Chyna and is the father of her first child, son King Cairo. After Kylie and Tyga officially became an item, the women digitally flung shade at each other—Chyna poking fun at Kylie's plump pout while Kylie seemingly mimicked one of Chyna's monochrome outfits.
Then, when news broke of Rob and Chyna's official relationship, a source told E! News, "Kylie doesn't want to give [Chyna] the attention she so obviously wants...Ky is ignoring her antics."
However, the ignoring didn't last long. After Rob and Chyna's surprise engagement, the two women reunited to let bygones be bygones—and wasted no time documenting the moment as evidence.
"We've all talked. I've met up with Kylie. Everybody is mature. We're not holding on to grudges. We've moved on," Chyna told People of their meeting. Rob was more than pleased at the relationship development.
"So happy my girls finally got to talk and make peace! #MyFamily #AllLove," he wrote on Instagram in a since-deleted post.
While it seemed like the dust had settled on the drama surrounding the siblings and their significant others, just a month later, Chyna released a set of Chymojis. Among the images included in the set was a Jenner look-alike, who Chyna was featured slapping. The symbol did not sit well among the sisters as Kourtney Kardashian called her brother to express her outrage.
"Everything with Rob, I always try to be super calm but I was just like in a mood," Kourtney told her makeup artist Mario on Keeping Up With the Kardashians. "So I was gonna call Chyna and then Kylie was like, 'No just call Rob, it's too crazy to call Chyna.' And I'm like I don't want to yell at a pregnant person."
Upon talking to Kourtney, the dad-to-be was upset and denied that the Chymoji was of Kylie. According to Kourt, Rob said, "I'm gonna go on the red carpet tonight and I'm gonna tell everybody how I have the worst, most unsupportive, disgusting family."
While it turned out to be an empty threat, we have not yet learned why Rob took aim at Kylie instead of all of his sisters this time around for Chyna's recent missing invitation.
