Rob Kardashian Reportedly "Convinced" Blac Chyna Is Going to Ditch Him for a Rapper

Another day, another alleged bummer surrounding confirmed royal couple Blac Chyna and Rob Kardashian. The latest ChyRo development adds another semi-confusing layer of turmoil to this whole love thing, as TMZ reported Thursday that Kardashian is "convinced" Chyna is going to "leave him for a rapper."

Sources claim that Kardashian and Chyna have been "fighting for months," which adds more alleged weight to previous reports of the couple having a rocky summer. Kardashian is reportedly not super comfortable with certain aspects of Chyna's past, including her relationships with Future and Tyga. Tyga, of course, has since moved on with Kylie Jenner.

TMZ's sources also said Kardashian has insisted Chyna not listen to certain songs when they're hanging out, claiming he once told her she'd "rather date a rapper than a fat Armenian." Whenever Chyna brings up topics like workouts and other fitness concerns, Kardashian reportedly "takes it as an insult" and the conversation gets "tense."

These alleged AF developments come just hours after E! Newsconfirmed Kardashian and Chyna were "fine," despite the recent flood of breakup rumors. "Rob and Chyna are fine," the source with no name said Wednesday. "They are together, but it's just difficult right now." Part of that difficulty, the source added, is that there was apparently some serious confusion surrounding a recent baby shower invitation:

During allegedly happier times, Kardashian praised Chyna for helping him through some serious life shit. "[Chyna] got me through my darkest times," Kardashian toldPeople as part of a cover story this summer. "I wasn't happy in my own skin. I missed out on so many things."
