Blac Chyna, Rob Kardashian Dating Rumors Enrage Kylie Jenner

Rob Kardashian is rumored to be dating hip-hop model and longtime family nemesis Blac Chyna, prompting his younger sister Kylie Jenner to compare him to Satan.

TMZ reports Chyna recently posted a picture to Instagram with some unknown man's heavily tattooed arm draped around her, which she captioned "the beginning." The website adds the tats on the arm of the man in the picture bear a striking resemblance to those known to be sported by Kardashian.

Sources later claimed Chyna and Kardashian have been virtually inseparable over the last several days.

"They've been hanging out," a source told Us Weekly. "Not sure what to call it yet, but they are hanging out. There's a romantic vibe there."

After hearing the news, Yahoo reports Jenner instantly posted and later deleted a photo of a Baphomet, a three-eyed goat typically associated with the devil. She captioned the photo, "This is @robkardashian lol."

Jenner's feud with Chyna has become legendary. The conflict stems from the fact Jenner's rap star boyfriend Tyga once dated Chyna and shares a 3-year-old son with her.

Chyna was also once close to Kim Kardashian, but that relationship quickly dissolved after the now 18-year-old Jenner took up with the much older "Rack City" rapper in late 2014.

Since then, Jenner and Chyna have bitterly feuded, with much of their battle playing out on social media. At one point, Radar Online reports Jenner taunted her nemesis by pointing out Tyga had gifted her with a ring, presumably as a symbol of their commitment.

In recent months, Rob Kardashian has kept a low profile after gaining more than 100 pounds over the course of just three years. According to TMZ, he was diagnosed with diabetes after feeling ill and being rushed to the hospital.

Before then, he had last been seen in public sometime in June at an In-N-Out Burger.
