“Keeping Up With the Kardashians” star Rob Kardashian is afraid Blac Chyna will leave him for a rapper, TMZ wrote Thursday. She previously dated lyricists like Future and, most notably, Kylie Jenner’s boyfriend, Tyga.

“You'd rather date a rapper than a fat Armenian,” Kardashian told Chyna, according to a source. Now, she’s not allowed to listen to certain songs when he’s around.

Kardashian and Chyna aren't living together anymore. “They are living separately because that makes for a more harmonious life for the two of them. They just bicker a lot. They argue but ultimately they love one another,” a source told E! Online Wednesday.

But Chyna isn't the only person he's apparently having problems with. He took to Instagram Wednesday to slam rumors about her baby shower. “This sounds very fake lol. 100 percent of this story isn't true at all haha and u said almost never walking out the front door. I park my car in my garage why would I walk out the front door,” the Arthur George sock designer wrote. It was not clear which story he was referencing.

“Y'all be just making anything up man and I'm slipping into a black hole hahahahaha I been in another dimension for like 5 years lol and I weigh 295 and been that way for a while I am not tripping and Chyna didn't have even have her baby shower yet you guys are on that good s---. What kind of drugs makes u make up these stories? I just need to know where I can get some??? Please tell me.”

Later Wednesday, Kardashian shared a video of his fiancée’s burgeoning baby bump on Snapchat. He wanted to capture his daughter moving, but she was camera shy on this occasion.

The couple’s reality show, “Rob & Chyna,” airs Sundays at 9 p.m. EDT on E!
