Blac Chyna’s case against the Kardashian clan may just be valid after leaked old emails between Khloe Kardashian and KylieJenner revealed that the sisters threatened to get “Rob & Chyna” cancelled.

In the emails, which were obtained by radaronline, Kylie refers to Blac Chyna as “toxic” and “fake,” and said that she felt “very strongly about cancelling season 2 for Rob & Chyna.” The emails were sent in December 2016.

“The reason Chyna wants to be with my brother is for this show,” Kylie claimed in the email. “She does not love Rob and their relationship is too fake and destructive.”

Another email from Khloe to Kylie and others showed that she threatened to stop filming “Keeping Up With the Kardashians,”

if the network didn’t cancel Chyna’s show. “We are even considering not moving forward with our show if theirs continues. That’s how strongly we feel this is damaging to our family,” Khloe wrote.

In one of the emails, Kylie said she would make up for all the cancelled Rob & Chyna episodes by giving more storylines.

“We all know filming isn’t my favourite but I will sacrifice and promise you guys episodes and stories,” Kylie said.

She also harped on her brother and Chyna’s then relationship.

“The public has been exposed to what fake a relationship they have and it’s embarrassing and makes us all look fake,” Kylie said. “The show is giving this toxic woman money and exposure she lives and breathes for… Her association is detrimental to our family and Keeping Up With the Kardashians.”

Khloe said she was concerned for Rob’s safety and the credibility of the brand due to his show with Chyna.

According to a source close to Chyna, the “smoking gun” emails were a bombshell revelation for her case.

“Chyna knew that Rob’s family was trying to shut her showdown and this is the proof that everyone was involved,” the source told Radar.

Chyna first filed the lawsuit in October 2017, claiming the family conspired to get her show cancelled. A trial date has been scheduled for February 2020.
