The Kardashian clan may not be invited to Rob Kardashian' s wedding to Blac Chyna, at least that is if his future mother-in-law has anything to do with it. While the couple were seen out together in Calabasas just a day after announcing their engagement, Blac's mother Tokyo Toni was quick to have some fun at the expense of the Kardashian sisters adding that they will never be invited to her daughter's wedding.

Posting a mocked up picture of Kim, Khloe and Kourtney holding onto Blac's wedding dress in tears she launched into a tirade of abuse at the reality TV stars. She wrote: "This is funny!! However!! Her train would be so long they assess would be in the Michigan triangle holding it and miss the wedding!! That's how far back they will be!! " Shots fired" oh well!! It's social media!! And all these reality h**s are " Boxed or botched!!. Bonus - You not even going to be invited! I didn't see the invitation ! Ps' To all her fake ass friends!! " Oh b***h I see you and NO b***h will ever plan my daughters wedding but "Me" or her! #ps or her bestie - Whoever that is? (sic)'

Blac's mother also makes jibes about their Armenian heritage saying: "PS -,they are Armenian so no blonde hair blue eyes over here wheneva they do have a kid!! Let's get it poppin now!! Lol!! Okay whenever y'hall ready but get the point (sic)"

While none of the Kardashians have reacted to the engagement news, a source told Us Weekly that Rob's mom Kris Jenner said he's 'making a mistake' by rushing into marriage.

According to Mail Online, on the night Rob and Blac revealed their engagement news to the world Kris, 60, and her daughters set off to Vail Coloroado for a family ski trip .The siblings and the Kardashian matriarch are apparently not taking the marriage plans seriously, claiming that Rob has a reputation for being a "serial proposer" after previously popping the question to exes Rita Ora and Adrienne Bailon.

However, it is thought the Kardashian women are meeting for crisis talks amidst fears that Rob's defection from the family fold and the complicated dynamics that have resulted from his relationship with Chyna - who has a child with his sister Kylie's boyfriend Tyga - along with the cancellation of Khloe's chat show, threaten to weaken the Kardashian brand.

Rumours that Kardashian, 29, popped the question were fuelled when Blac Chyna posted a photo of herself on Instagram wearing a large diamond ring on her engagement finger. In the photo, Blac Chyna, real name Angela White, can be seen grabbing Kardashian's face alongside the cryptic caption: "YES !...!...!" The couple, who only began dating in January 2016, are yet to officially confirm the engagement news.
