Sleeping With The Enemy! Rob Goes Public With Blac Chyna In Shocking New Instagram

Keeping up with the Kardashians outcast Rob Kardashian has caused a war between his already fractured family by dating the clan's worst enemy, Blac Chyna. Now, one day after their relationship became public knowledge, RadarOnline.com has exclusively learned from a source close to the overweight 28-year-old that "he was the one to pursue her!"

"Rob was the one that went after Blac and not the other way around," said a source close to the family. "He thinks she is super-hot and she is very much his type."

Those who keep up know that Blac Chyna, 27, is the baby mama to 18-year-old plastic princess Kylie Jenner's on-again, off-again boyfriend Tyga, 26.

After recently deleting all of his Instagram posts, Rob posted a photo on his page this morning that joked that Blac Chyna may be pregnant with his first child.

In the photo, his new lady-love is seen carrying a baby car seat. The caption of the meme read, "Blac Chyna probably out shopping right now as she plans to give birth to the ONLY next generation of the Kardashian name. #BabyKardashian"

Why the blatant blast to his family, who have feuded with his new woman for months?

"Rob does not care about what his family or anyone else thinks of this because he is really into her," the insider told Radar.

"He honestly believes that her intentions are pure. They have been spending a lot of time together at her house because Khloe would never allow Blac Chyna on her property."
